Evasion,
You have really hard decision! All three are very well designed and made knives and each would serve you flawlessly. So the decision depends on your personal preferences only. I'll try to tip up some points of difference, thinking about them could make your decision easier (I hope
)
Handle material. 710 Axis Lock and 800 AFCK have G-10 scales and 750 Pinnacle has bead blasted anodized titanium handle. Think what you like more in your palm.
Handle shape. Pinnacle and AFCK are handling quite differently (for me at least), 710 even much more differently. Here is nothing to describe, simply try to handle each and compare your impressions.
Handle strength and flexibility. Pinnacles handle is considerable the strongest among theses three knives and AFCK handle is the most flexible in blade's plane. Think how essential is this point for you. For ex. I'm continuing to carry my AFCK (although I have all three knives) because I have no intentions to use my urban-carry knife as a prybar but for cutting purposes all three knives are strong adequately.
Blade shape. 710 and 750 both have the blades with noticeable recurve. This adds some cutting force but makes them more difficult to resharpen, especially if you have flat benchstones only. The new Eze-Lap folding diamond sharpener with oval surface could be solution in this matter. AFCK blade can be sharpened on each high quality benchstone without any problems.
Blade steel. 710 and AFCK are available with ATS-34 or M2 blades but 750 - with ATS-34 only, so far. It is no noticeable difference in edge retention and cutting abilities when cutting. But M2 blade could be more impact resistant and less prone to chipping when hits some hard thing. On the other hand the M2 blade is more expensive.
Price, of course if it is the matter for you. Difference between 710 with M2 blade and the less expensive AFCK with non-coated ATS-34 blade could be about $30-40 in retail.
Locking device. Axis Lock here is a clear winner, please see my reviews:

I tried to explain and justify my opinion. I could put Mono-Lock at the second place in strength competition but I'm still going with my AFCK. Maybe I'm simply stubborn as a mule...
Carry mode. 710 is designed for tip-up carry, 750 and AFCK - for tip-down.
Truly ambidextrous is 710 only. You can open AFCK with left hand but you can not remove the clip on the handle opposite side. 750 clip also can't be set up for left-hand carry and it has single-sided opening stud.
All three knives have mat black
pocket clips and stand above pocket edge no more than 15 mm.
I didn't bore your deadly just?
Now try to tip the points more essential for you and through away less essential. Try to handle all three knives, handling comfort is one of the most important knife properties in my opinion. Check your local law regulations, maybe model 705 or Mini-AFCK 812 would be more suitable for concealed carry.
Hope this could make your decision easier.
Or buy them all and add also BM Nimravus fixed blade for camping and hunting.
Whichever knife would you choose I would strongly recommend -
don't take it apart for cleaning! It will void of your warranty. For knife cleaning it's enough to wash it in running water, if no - wash it in sharp stream.
