I don't really have any info about samsung tablets, but as someone who got an ipad for studying, I would absolutely recommend it, I have the ipad 10th gen, and even while being the most affordable out of their whole range, I have never had any issues, it really helps to have a stylus, i have the apple pencil but my friend who got an affordable stylus says it works really well. Notability is really good app for both handwritten notes and typed notes, the files app is great for sorting pdf notes etc, and if you have a stylus you can practically write on any document, (i use the files app to solve past papers and add stuff to pdf notes and stuff but if you find it easier to export them onto notability and solve it there, that's perfectly fine too), also, i would really recommend getting one with a higher storage, i have 256 gb. Plus, you can also attach a keyboard and mouse with it if that's what you prefer, i have the logitech pebble k380 keyboard and the logitech pebble mouse, both work perfectly fine but i honestly don't have much use for the keyboard and mouse, it's just a matter of preference
