Does anyone have an iPad alternative suggestions? I'm really tired of iOS. Apple sucks.

All what I do on my iPad are just
writing shit on PDFs
using One Note once a while
use browser to download PDFs from moodle
Video call once or twice a month
Be able to do file backups

The most important feature for me will be the ability to write things on PDFs smoothly in quantity, preferable if I don't need to download any extra software for that. Anything else I'm willing to work around it. Price Range below 500€ preferable around 200€

Please save me from using ever iOS again in my life.

@Hikari maybe a used remarkable 2? except the video calls. it doesn’t run android.
@uint8_t have seen it, don't like it. I need proper colour contrast for my dyslexia. And it's mostly just for writing, not writing on PDFs which are actually different. And it needs some broad compatibilities for me to use it for the university, which will be the main job of my tablet.
