rockfj,
No direct experience with either but in general, compare the hydraulic pumping capacity of the two. (ignor the power steering capacity) While you're comparing, some manufacturers publish a thorough listing of various force and range of motions for their hoes.
Also, I assume that the 110 has a seat that turns around to use the hoe end. I've never used one that has a separate seat for the hoe, but it seems that it would be a pain to switch seats every time you reposition the tractor.
Another thing of interest to me at least is how long it takes to remove the hoe so you can use the tractor with another implement.
And as someone said, the hydraulic possibilities never end. Even on the hoe, you might want to add a hydraulic thumb...
