What's the best gaming laptop?

I need a high-performance laptop that's fully upgradable, with at least 32GB of RAM installed (expandable to 64GB). My budget is $2k (can spend a little more if necessary)
Avoid soldered RAM, locked configs, or mini-LED/OLED if it compromises upgradability or thermals. Prioritize brands like Framework, Lenovo Legion, or ASUS ROG with proven upgrade paths. No Chromebooks or Macs.
