Here are some pics

These pics show the relative sizes of the wings quite well.
KyroJoe, in answer to some of your questions:
"
If you were going to compare these two wings..which felt more like carving turns in deep powder snowboarding?" - They both feel like snowboards in powder to me. Hell, even my H5 feels like a snowboard. It's the first thing I thought of when I started foiling. They just feel like snowboards being ridden on different gradients of slope. If you want a looser feeling foil, then the 633 is the one for you. Is the infinity more "locked in" feeling? Yes, but not in a bad way. It's a surf foil don't forget. Surfers still like to turn when on waves.
"
Did you feel, as others have noted, that the sshot 76 really PIVOTS more instead of CARVES through the jibes?" - No, not at all. I just found I could pivot turn the foil when I needed to, but could also draw out a long smooth turn with ease. On the day though, the pivot turn was the better option as the wind was light and my kite was small. All foils should be able to carve a nice smooth gybe with a wide arc, but not all can do a tight pivot turn at slow speeds and stay on the foil throughout the arc. This wing does both very nicely.
I guess the title of the review is a little misleading. I really did focus most of it on the Infinity 76, but this was due to the fact that the Moses 633 is currently the most Hyped wing in the foiling universe at the moment. You can read mountains of info from frothing foilers on various international forums like Kiteforum. The 633 has about a 30 page thread on KF how this wing will basically bring world peace and end poverty. The Infinity, on the other hand, had very little in the way of reviews for kiting applications. Plenty of stuff on prone and wake applications but that's not the info I wanted hence the need to demo. When I got the chance to demo both back to back, I was really excited to try the Moses 633 due to the world wide hype. I was already a convert to it before even trying it. The surprise for me was that after 1.5hrs on the SS Infinity, when I jumped on the Moses 633, my initial thoughts weren't - "oh yeah, this is SOOO much better", it was more like, "yeah, this is really nice as well".
