iPad vs Android tablets

I have used both iPad Pro and air and found logos buggy on both. Went to android s9+ and it ran so much better. Dare I say smoothe ? The issue with that particular tablet was that it was too long. If I relaxed my wrists at all it would want to fall backwards. Became quite annoying after some time. So I went back to the IPad Pro with the s4 10” …love the tablet, but the app has me speaking under my breath. Anything I can do to help setting wise. Besides updating that is. Issues vary but most often immediately noticeable is highlighting or notes etc. I reset it, and it’s fine, but it just keeps happening!
