Welcome to this forum. My wife and I have seven (7) active computers. Six of them run EndeavourOS and they have done so since August 2019.
The last one, a media computer in our home theater, runs Manjaro; it was set up in April 2019 (before EndeavourOS was introduced).
I have most of them (the exception being my wife’s main computer) set to look exactly alike, with almost all having the same programs installed. And they all work equally well.
I have been saying repeatedly that, one of these days, I will switch the media computer over to EndeavourOS (just to keep things simple) but, as it functions perfectly (and has done so for over a year and a half now), I am in no rush to do so.
NONE of these computers has ever “crashed” and we update our main EndeavourOS computers every day, once a day, in the morning.
The others (“travel” computers, “spare” computers) are updated less frequently (maybe two or three times a week) and the media computer in the home theater (Manjaro) is updated only once every two weeks or so.
We have a lot of programs installed onto these computers (as I said, they all have the same programs for the most part) and, as I also said, we have had absolutely NO problems whatsoever with any of them.
Manjaro is a fine operating system and, if EndeavourOS didn’t exist, I think we’d be using Manjaro on all of our computers.
But EndeavourOS DOES exist and both my wife and I like it better. One of the reasons (only one of the reasons) we prefer EndeavourOS is the fact that the programs, and, especially, the kernel, are the latest and best. (We also have an LTS kernel installed “just in case” but we’ve NEVER had to use it!) I also like the fact that, unlike Manjaro, the latest kernel versions are installed automatically in EndeavourOS (with Manjaro it is often necessary to manually install the latest available kernel). Note too that no “beta” or 'rc" kernels are installed in EndeavourOS.
Those are our opinions of course. And I must repeat that Manjaro is a very fine operating system, one of the best out there. But I think that, if you give EndeavourOS a fair chance, you will appreciate it even more than Manjaro and will like it as much as we do.
I wish you all the best.
