I don't know, I think it really depends on the person and the extent of the disease. Someone can have mild Crohn's or severe UC and vice versa.
To be honest, I always got kind of offended when people said "well at least it's not Crohn's" like my disease isn't as bad and I must not be suffering as much. I agree, UC is better in the fact that it CAN be cured by surgery, where crohn's cannot. Other than that... I mean, we have continued inflammation, bleeding ulcers, and all the other fun stuff... And even though I don't have Crohn's, I still managed to get GERD and gastritis and usually have at least two painful ulcers in my mouth at all times, so my entire digestive tract is effected except for the small intestine.
Here's a website that talks about
some of the differences in the two diseases: http://ibdcrohns.about
