Should i upgrade my osu tablet?

I've recently been getting into osu a lot. I use a Huion H640P. I don't know that much about tablets and i've been thinking of getting a new one. Should i upgrade? And if so, could you reccomend some good devices? Budget isn't really an issue (especially since from what i have seen, osu tablets aren't really all that expensive) Thanks in advance!

EDIT: Thanks for all the suggestions! I'll look into it right away :))
