EndeavourOS and Garuda are the same distro with a different default KDE theme, which you can install on any distro with KDE.

I personally would recommend vanilla arch, use arch-install command if you don’t want to do it manually. Then spend some time making it truly yours. At least if you wanna be on Arch, which is the best distro for ricing, finding software easily and having to learn a few things every now and then in case something break, as Arch needs some maintenance.

Now you may argue that EOS and Garuda are easier Arch installs with some defaults, but if you’re gonna be on Arch then the first time is best if it’s vanilla Arch, learn what you want and what you don’t, learn how the Arch way is done on there, and then when you have done that but can’t be arsed to do it again and again every time something breaks and you go for a reinstall, then go for the easier way.

If you just want recent software and none if the hassle of Arch then just go with Fedora KDE, OpenSUSE Tumbkeweed/Slowroll, or any of the trillion of distros, including Debian Testing.

Garuda and EndeavourOS are literally the same distro with a different default KDE theme. You can go to KDE settings, themes and search sweet candy or sweet Mars or whatever it was called and install it on EOS.

Maybe Garuda has the chaotic AUR by default I don’t remember but since you’re still on Arch and therefore expected to rtfm you should probably just figure out how to install it on EOS instead tbh, assuming you really want/need it
