It's not that people generally say "basic" ... they say "boring". It's designed to just work and be stable with some nice features but it has a slower release speed and the dev, intentionally, keeps things slow so that they can polish up all the features before they go mainstream on it. So it isn't doing anything revolutionary and it isn't giving you bleeding edge everything... it's just nice and stable. It's become one of top recommended distros for a reason.

The main hiccups I see with it is that they are lagging behind on Wayland support... which is slowly becoming the defacto standard for desktop display tech. If you aren't really up on the x11 vs wayland debate... this likely isn't even an issue for you. Suffice to say they've tried to hang back on x11 for a while, which is the older but much more thoroughly tested way of doing the user space display. Secondly would be... because it's a slow burn on updates, you might not get the latest greatest updates for the kernel with the display drivers. So for gaming that could make things a little more finicky. People do use it for gaming... so don't think it can't be also used for that, just might run into hiccups.

Good thing is you can test it out, and if it doesn't work out, try something else.
