In my experience everything already had drivers installed on linux. I think with the logitech stuff you mean the stupid configuration ui that would perfectly work on linux but they choose to not port it(you can still use it with wine for example). All my keyboards have qmk so that works on linux. A github project is much less shady because you can check the source code. Idk whats wrong with your trackpad. Battery life is hit or miss on linux, i get more hours on linux currently but only after installing some stuff. On ubuntu or mint the battery life should be good out of the box. Anticheat is basically anti-linux so ofc it wont work. For me backwards compatibility is better on linux than windows. When i try to run old software on windows it never works. Software support is pretty good nowadays but some professional stuff wont work. If you do that you should go mac lol.
