Yes its way bigger! I prefer the wacom glass as it feels a little big more matte, with huion i had problems getting used to it without the screen protector. The smoothness wacom seems to be smoother and the glass is thinner so the actual pen is closer to the actual painting so it feels like you are drawing directly on the screen. Also the 27' one has a small controller with keys which you can set the shortcuts. Its the first time im not using my keyboard and its a little weird but you can put so many things on it that its actually much easier!! Thank you!
