iPad Air vs iPad Pro

Hi. I currently have 9th gen iPad and I want to upgrade so I can get things done like on my Mac instead of just watching content. I have m1 MacBook Air and 60hz panel don't bother me at all but I wonder if iPad Air screen is the same in terms of quality? Also 128gb on m4 iPad Air is looking bad, the m5 ipad pro starts at 256 gigs and it's better in almost everything. I want to try some software on iPad like logic, Final Cut, procreate etc. Is 128 gigs enough? And is the screen good enough for watching anime and stuff? I don't wanna replace my computer with iPad, I wanna use it like it's intended to. Oh and one more thing, is pro that much better in terms of battery life?
