Legion Go Gen 2, or Legion Go S Z2 on Window 11. Z1 Extreme is sold out in Canada.

I'm trying to decide if I should get the Legion Go Gen 2. I have an Alienware M18 Intel I9 13900 paired with a RTX 4070 64 GB RAM and 2TB SSD. I also have a PS5 that collects dust. I just don't have the time to play on my PS5 anymore and mainly been using my Alienware for work stuff. I just want a handheld that I can use on my couch, or bed for a quick play before I sleep.

I'm wondering if I should go with the Legion Go 2, or could I get away with the Z2 Go with Windows 11 since the Legion Go S Z1 extreme is sold out in Canada? With my vision I doubt I'd realize all the performance of the OLED screen. I can get the Z2 from Costco for $949 Canadian or just pay up and wait for the Gen 2 for $1499. Anyone who had any input would be greatly appreciated.
