What ipad should i get? Taking notes, watch and games

Hello, i want to use it for playing like ragnarok and study my deal breaker is the non laminated for ipad a16, 256gb for 27,900 but its good for its price i also read some reviews about it lagging after 2-3 years.

My other choice is getting ipad air M4, 256gb i know it would be very very good compare to the ipad a16 but i think the price is too much like 49,990. Is it really worth it?

PS. My other choice is just getting ipad air M3 for 39,990 since its much cheaper than M4 but i cant find stocks anywhere 😭
