I have the KB2365 backhoe on my CK20HST and it works great. No real problems, just keeping fittings tight so there are no leaks is important.
From my observations, not use, of the Woods backhoes is that they may be better built than the Kioti hoes. If purchasing a 4 point hook up, one gets better ground clearance. The mounts seem beefier as does much of the rest of the hoe. Woods seems to do a better job of making the tolerances correct as relates to mounting and assembly holes as well.
As you may know, the Kioti subframe(which comes off with the backhoe) clearance is a few inches less than the Woods 4point mount in which the subframe portion stays on the tractor when the hoe is removed.
If you're planning to have a mid mount finish mower, you would want to buy the Woods as it can be used in conjunction with the mower. Not so with the Kioti hoe.
