Hmmm... good question, Raj.
I use a single 19" monitor, and am quite comfortable with my 4x5. My partner has a 21" monitor with a 6x8 tablet, and he's very comfortable with it, but I'm not. I find I have to move my arm way too much, and it's too slow to get from one side of the screen to the other. I have fairly small hands, and his are moderately large. That might have something to do with it.
You might want to try to figure this out based on your hand size and monitor size, but the best way, I'd think, would be to see if you can try both out somewhere.
