As I asked in the titles, I’m not asking which one’s better , but which is your choice and why ?
Also I’m not decided either, should I get xfce, gnome or KDE since the external SSD will be slower and I need the total size of the OS to be smaller so it boots faster, cuz the whole Linux os will run through a usb 3.1 cable
The same question applies to grub vs systemD, which one boots faster ?
This would depend on the type of work flow you are used to and the work flow you are looking for. Us telling you what we use wont help you figure out your work flow.
This would be dependent on the work flow you desire and what other apps you install along with the OS. A WM is going to have a smaller footprint than a full fledge DE but a WM is going to be minimal and may not have everything you want.
if you are only asking about the “why” then it’s easy: headaches with grub far outnumber my headaches with bootloader.
uefi over legacy any day.
but I know one better than the other so there is an inherent bias built into any subjective question you ask.
that’s why I won’t touch DE question with a 10 foot pole. but budgie since you asked (eye candy, uncomplicated, dependable & never buggy). I don’t like KDE or K packages or the lifestyle, Maybe someday. I give everything a chance. I’ve not exhausted the gnome/gtk life I really still like it.
I gave you a thumbs up because I value your research method: cast a wide net, then mull it over.
