The subframe types are thought to be less mechanical stress on the tractor. There has been some breakage reported for both styles.
My NH tc40 has the subframe type. It's a NH 758 hoe. Like mikim said, the mounting would be much easier with a carrier on casters, but it usually takes me ~30 minutes to mount mine from start to finish. The hoe weighs about 1700 pounds, so forget moving it by hand when it's off the tractor.
Storage of the NH subframe type can be a space eater because the c-channel frames that extend under the tractor stays with the hoe and that means it covers 4-5 feet of floor space just for that when it is unmounted.
The only clearance issues I have had is to make sure to tie up the hydraulic lines tight to the tractor. They like to snag stuff in the woods. I don't think any part of the subframe or hoe is lower than the front axle differential clearance.

When I was shopping for a hoe I narrowed it down to the NH758 or the woods 80x. That long subframe that has to be removed with the 758 and "put somewhere" was actually the primary reason I went with the woods. There wasn't much difference between them otherwise.
