1- Arch
2- Fedora Workstation and pre-release (Rawhide, rolling)
3- MX
I’m still up for a thorough first testing of
X- OpenSuse (Tumbleweed, rolling). A first hour of testing does not look very promising but rather hastle-some, compared to the above DEs’ ease of use. The implemented Yast seems a real drag on first look, reminding of Gnome- and Knome- software (diskover), but only much worse.
That’s why I purposely took Gecko based on “Leap”. “Tumbleweed” seems to be an impressive mess, sometime ago I tried Gecko earlier with Cinnamon D.E. but it was too clunky for my taste. Also discovered the most backward “sudo” in history, I have to give the regular user’s password only for going into this system! One good thing is I don’t have to create a text file into “/etc/sudoers.d” but meh. But because I have to go even deeper… there’s almost no time and I have others that keep me busier…
LOL to me YaST Software Manager is a thousand times better than Discover. None of those others and Pamac for me; I actually forced myself to learn things about “dnf”, “eopkg”, “pacman”, “zypper” and other such programs because my experience with those slow GUI programs was bad to say the least possible. With YaST it’s acceptable but Synaptics on Debian and ALT Linux Sisyphus, and GSlapt on Salix were a little bit better.
One more thing: if you’re bothered by package managers and installers don’t try Mageia “Cauldron”!
The Solus command-line package manager was also backward, enough said. Sorry for the O.T. and TL;DR
Currently I’m using mostly EndeavourOS but I am also using Siduction because it’s rolling right up to date.
As far as package managers go there are a lot of distributions that use discover on KDE and i have no issue with it. Siduction has it installed also on KDE.
I could use any Linux distro but i want rolling with most up to date kernel. I’m not an lts kernel user nor do i suggest installing an lts kernel the minute something doesn’t work.
I like a bunch of linux distributions each for their own differences but my main go to is EndeavourOS.
I use EOS Sway at the moment but I’d probably look to KDE neon or the upcoming Fedora Sway spin. I like the Ubuntu Sway remix but I much prefer newer packages.
I suppose I’d be using Mint if I wasn’t using EOS. That or vanilla Arch. I last used Mint nearly a decade ago and I actually really liked it, it was a critical step in transitioning me away from Windows for good.
Pure Arch. If that’s not an option, then Fedora.
oh?.. I thought Arch is developed by a team of people, I thought it’s community-based like EndeavourOS… is it not?
arch linux is full of volunteers of course 
but bunch of loveonce to develop, also project leader got voted , but how long or short idk
I use a mix of Debian Testing and EndeavourOS both seem very stable. I really like that EOS as it is very easy to install, pacman is fast, not a lot extra stuff that one does not want.
1 Endeavour Os - LXDE
2 Arch - MATE
3 Mx Linux - KDE
I have made many leaps across distributions. So much so that I got tired of it, and I still haven’t found the perfect one. Until I came across this forum. I have two systems on disks, the third saved in a live session made from a snapshot of an already configured system.
although I have to do justice, as Manjaro and then Mabox also drew me in for a long time. I still have a weakness for Mabox to this day
really impressed from Alpine Linux
I will use it for a VM
Sorry for late reply, yes it inherits all the issue with Ubuntu but but all the issue is exists in certain distro my guy, for example if somehow gnome have issue in ubuntu, you don’t have to experience it in other ubuntu distro that is not using gnome.
The reason arch so low on the list is because i already mentioned it above, and it’s kinda my last stop if any of the choice above is have some issue here and there.
Being in last place is good, since i had no choice but to install it rather than using it and then go to another one, if arch have issue i’m just going to reinstall again.
My very first distro is Suse (not Open Suse) from jewel 6 cd box set on my first pc , 486 dx2 66mhz… Legacy Suse is too hard for beginner, but I’m able to landing on X after tons of trial & errors, good 1998 times 
with no smart things and less internet available.
After I growth indeed Debian carry me trough 2000/2020 era. Simply the best for me. 
So I had been using Kubuntu for some time and I was largely happy with it - but then I ran into some weird problems (where I used Ubuntu) regarding some updated security issues. Me and most of my peers work on Ubuntu on Virtual Box. For some reason the whole installation mechanism broke for all of us simultaneously. I tried, along with my peers to get it to work (since it is linux) but couldn’t and decided to do a fresh install.
The fact that all the LTS (I think it was 21.04 but don’t quote me on this) broke without any clear mechanism to get it working again really put me off debian so I’ve been looking for alternatives and a friend of mine introduced me to Arch - and pacman - and their philosophy of rolling piecemeal release.
I’ve since looked at two potential candidates - Manjaro (which from what I’ve read is a great entry level distro for those wanting to experience Arch) and Endeavour OS. I decided to go with Endeavour OS because I like the dark purple theme and space-travel wall paper 
But I’m loving these forums and I love how easy everything is to get to work and fix - and I love the slim install bundle along with these beautiful themes - Also I love how easy it is to experiment with something like xfce, kde etc while staying within EOS.
But yeah - Manjaro would be the next candidate
Slackware and Arch-Linux
Debian “testing” until “Bookworm” becomes official LOL. But not with KDE Plasma, not v5.24 or later.
A short time ago it would have been Manjaro KDE but I couldn’t stand it on my other laptop, decided I couldn’t go rolling-release there if I seldom use it. 
I’ve been emphasizing Manjaro MATE, Spiral KDE and Kubuntu besides EndeavourOS. Slowly and steadily taken in, despite my obstinate resistance… you. Will. Be. Assimilated. Yeah that will end with Plasma v6 LOL. I’m willing to use even the v5.18 I found with Freespire. No! Now… must… start… new… desktop… (beep over and out)
Endeavour os, OpenSuse and Zorin
