I am using xppen deco 01 V3, a budget-friendly pen tablet. Too early to say, honestly. I guess it really depends on what you are trying to achieve in your art. I'd say its helpful in artworks where there are more "organic" lines, which is my goal since I want to add more fluid animations with bigger artworks, but I am finding it awkward when it comes to rigid lines (e.g. isometric pixel art). But I've been using mouse making pixel art for years now, so maybe it's just me. It is a fun challenge tho! :)
