Also fair but again power budgets, handheld the Switch uses about 7-8W max (online play) total system from my own battery life use, docked 15W give or take for the entire system. The Ally uses about 25W total in the 15W TDP mode, Steam Deck is about 32W average at 15W (40Wh battery, 1.25 hour total time = 32W):
Might have changed as it's a may 2023 video but big total power draw differences are difficult to make up, although at low power the Ally is very underwhelming vs deck so I expect a big advantage for the Switch successor there. Higher TDPs like 25W should still favour the Ally for a couple years but by 2030 I expect the Switch 2 to pull ahead. But if handheld PCs are being made newer versions should have a good lead so whatever floats your boat
