Just use the 120w on both…

Of course something that needs 120w isn’t going to be able to be be powered by a 90w supply.

This is not a problem. Frankly it sounds like you don’t understand how electricity works.

I use the same USB-C GaN charger for all of my devices including MacBook Pro and Sony A7RIV. It’s 200W…

Just buy a big enough charger and you’re good.

That might be true for desktops (and even these could very well throttle their TDP based on available power), but most laptops I know can actually just supply the difference from their battery.

I personally just wouldn't get a laptop that can't run on a much more compact lower power wall adapter. Being able to use a tiny 20W power brick in a pinch is great.
