For me its an easy decision - ill take the performance all day long.
My gaming laptop is essentially my gaming PC that I take with me while im away. So the fastest GPU / CPU combo i can afford is #1 priority, probably then followed by the screen, as the RAM & storage i can upgrade myself. I don't mind the weight - id sooner lug something heavy around with me that performs great than have a feather-light 'gaming' laptop that's constantly bouncing on thermal limits. I have an MSI Vector that ticks all of these boxes- its heavy but the cooling system works well & performance on its RTX4080 is stellar (I hit 50,000 on Firestrike graphics score)
