Query about your linux daily drivers?

So i have my main system, i have been running NixOS on for over a year. It has been a pleasure to daily drive. And ive recently been playing with gentoo and funtoo. And althought alot of information, which is somewhat overwhelming but is slowly growing on me and making me appreatate linux as a whole. So i was wondring what other software users run, and what hardware they run it on. Ive also been looking into replacing my lenovo W540 because the Nvidia K110m is royal pain and kills my battery life. Ive been looking at lenovos t480, t480s t440p. And cant decide, i really would like at least 4 cores, good linux support and long battery life aswell as repairablility. The laptop is going to mostly be a web browsing machine aswell as trying out gentoo and new distros. If you have any suggestions on a laptop id very be much grateful.

Cheers,
