I am a Linux noobie and have only used Mint for around six months now. While I have definitely learned a lot, I don't have the time to always be doing crazy power user stuff and just want something that works out of the box.
While I love Mint, I want to try out other decently easy to use distros as well, specifically not based on Ubuntu, so no Pop OS.
Is Manjaro a possibly good distro for me to check out?
I run linux on my gaming rig. I've had the best luck with performance of graphics cards with manjaro and pop. I am not a huge fan of gnome and prefer kde (FWIW, gnome works fine, I just prefer the feel of kde).
With the above in mind, I really like the newness of the packages on rolling distros like Manjaro/arch. Yes, it can break things but Manjaro tends to be a bit behind Arch on releases -- maybe this helps? The AUR is awesome. I also like several of the gui tools Manjaro has implemented to make graphics driver installs simpler.
Pop worked really well and was simplier for gaming -- especially on devices with hybrid graphics.
That being said, I haven't used Mint since the forums were hacked. I haven't used Ubuntu since they started devaluing their users (integrated Amazon?, forcing snap?). Fedora is nice but I found pop/manjaro better for gaming due to graphics support.
My advice to you -- what you are asking is one of the main benefits of linux -- personal choice.
So... get out your USB stick and try them. Use the forums to help you with the nuances and make each work for your needs. Then see what you prefer. Then donate to that project and its base project.
