Unfortunately I have no picture of a 710 and 705/707 together, but I own/have handled both, and couldn't really see myself carrying a 705/707 except as a backup knife, or knife to use in mixed company. I doubt I would ever carry one as my primary use knife. Why? The handle's just too small for me. Admittedly the 710 is a bit bigger than I normally need, but I prefer that to the lack of space for all fingers on the 705/707.
I rarely carry just one knife, but between the 710 and 705/707, I would go with the 710 if I had to choose only one. However, between the 710 and 943, I would lean towards the 943 on most days. In my opinion both knives carry about equally well in the pocket (with a slight edge to the 943), but the 943 is less likely to intimidate people (almost looks like a kitchen paring knife out of the corner of the eye, I'd say), and is easier to handle. That is, with a handle that fits all fingers, and without excessive extra space, I find the 943 to be generally easier to open/close, change grip, and put to use in fairly tame EDC tasks.
But, with all that being said, my 710HSSR is definitely my go-to knife for hard use. It's a little more slender than would be optimal for true hard use (for that, I'd look towards a 420 or 520), but it more than makes up for that by sheer cutting ability (not to mention superb edge holding of the M2).
So I'd recommend choosing between the two based on what you expect to do with it. If you are mostly going to use it around an office, in the kitchen, opening mail, in restaurants, etc., then I would say to go for the 943 (and I do think it could handle the occasional tougher task, if you're worried about that). But if you're working in a warehouse, or camping frequently, or doing work in a shop, basically anything with more regular hard use, go for the 710. But if you're looking for super-compact, lightweight carry, combined with great resistance to wear on the handles, then by all means, track down a 705 (the HK 14210 by BM would be a much easier to find alternative, and somehow it speaks hard use to me more than the 705, while still being a great compact knife).
Sorry for the lengthy post, and sorry I don't have helpful pictures (my sister's the one who owns the 707, and she's nowhere near). But hopefully there's some useful info in there somewhere.
