What is your budget? Any OS preferences? iOS / Android.
I''ve been using iPad with Apple Pencil and the writing experience is next level. I tried a few passive stylus and one active one too, Wacom Bamboo or something (dont remember exactly) before buying iPad and Apple Pencil. Have been using it for note taking, annotating PDFs etc. and I'm totally satisfied with it. Personally I don't like Apple products much, specially because of their high price but iPad is their only product which I find worth the money, just my opinion. The entry level iPad comes at around 30k (WiFi only) and it supports 1st gen Apple pencil which is priced at 10k. You might get some bank discount or Student Discount (Apple launched some student discount in India, dont know in detail, google it).
