Can someone please post a short list of the differences, as well as pros and cons for each model. I am mostly interested in ergonomics and quality.
806D2 is D2. 710 can be had in D2 (if you search hard), M2 (a standard) and 154CM (a standard).
710 has a higher primary grind, and a recurved blade. Both give you (theoretically) better slicing.
M2 in 710 is about as tough as you can get, but has NO stain resistance. It is a high-carbon steel.
710 grip works better than 806 for me in alternative grips -- ice pick, reverse (edge in, edge out, whatever), underhand (edge up), etc. For me, the 806 doesn't work as well in any grip than standard hammer, saber, etc.
806 has oval hole, 710 has stud (I like hole better).
806 seems to have a pointier... um.. point.
806 handle is longer than 710 (marginally) for almost NO increase in blade length.
Those are just a few. 806D2 generally goes with me when I'm headed into the woods to hike or camp, because it is about as close to a fixed blade I have found in a folder. 710HS (M2) goes with me into the yard or working on the cars, when I need the toughest, sharpest, longest edge holding, and best versatility for utility.
Hope all that helps. Much is subjective. I would not particularly recommend one over the other. If you already have the 806, you will be served by it as well as you would with the 710. BUT, if you tend to be a BM collector, like me

you definitely should add the 710HS to your stable.
