Everybody online said the non-plus-ultra was the iPad Pro, even compared to other name-brand devices from Samsung/Microsoft.

So I tried them both, and wow. 120fps and a screen optimized for low delay really makes an enormous difference.

With all other tablets, it was more a question of "well how more or less awkward does this feel to use", where that question didn't even come up with the iPad.

I know this sounds like shilling, but I recommend just trying it out on a real device sometime, even or especially if you have no intent of buying one.

Jokes aside, I'm happy I haven't had the same experience as you for gaming. Because then I would have to buy into high performance gaming. I can now happily play a game on something like Stadia or my old Macbook without having to feeling something is wrong or missing. Kinda like how watching movies on VHS was fine until HD came along. Now every artifact or resolution drop in a video is an annoyance.
