Hey, Jeff, you've gotten a lot of good advice here, but ultimately the choice is yours. I don't own either of the knives you are thinking about buying, but the 710HS is definitely on my list to buy. I do have the 942, which is also an axis lock design like the 710. In my opinion, there is no comparison between an axis and a liner lock. The lock is only one component of a knife, and you should not base your decision solely on lock style, but personally, I don't think I will ever by another liner lock. If you are really set on the design of the AFCK, then I would go with that, but otherwise, go with the 710-- I think you will be amazed with the axis. You should do searches in the current blade discussion and knife review forums as well as the archives for "axis" and "liner lock" before you make your decision. Good luck, and let us know what you decide.
