when i went to the apple store recently, i just happened to test out the pencil on the ipad, and let me tell you- it felt amazing. the pen was heavy and it glides across the glass so nicely... i almost considered scrapping my old wacom and invest in the set in the future. but at the same time after thinking... a tablet that's designed for drawing has express keys that can be useful if you're considering to be professional. (i dont see 9.5 inch i only see 9.7 inch. ipad pro 9.7 is around 400-500 bucks? and you gotta buy the pen if you wanna draw which is 100 bucks totaling 500-600 dollars. with that kind of money, you could get yourself a real good drawing tablet.
One good tip to help you decide is to figure out the total cost of your tablet, then compare to other tablets with similar price. Look at reviews and descriptions and compare which is better built or has what you need.
