Hi, daggers. I need suggestion

Old topic
-----------------------------------------------------
I planning to buy new wacom for replacing my old one which is small intuos 4. I aim for wacom intous pro but I'm confused which size should I buy. The thing I'm confused is that do the size of medium and large have lmpact gap on drawing precision? My monitor size is 22" and screen res 1080 by the way. 

Also i would gladly to hear   what other professional artist using on their setup on size monitor and size wacom they used

Thanks.
