I've been a very happy FW16 user, so much so that I got my partner an FW13 to replace her very old and very bulky gaming laptop. Similar specs to yours + AMD dGPU module. Recently cleaned the innards and upgraded my mainboard to the HX 370 in ~20min with zero issues. Compared to what I've been reading on various forums/threads, my experience as a whole has been virtually free of problems! FW + NixOS is a potent combo that squarely satisfies the kind of configurability/overall experience I need/want in the tech I use. (And perhaps more importantly, it handily assuages my paranoid mind.)
