Circling back since I finally made a decision and pulled the trigger -- got myself an Axis and I absolutely love it! 760 wing, 340 stab, short fuse, 90cm 16mm alu mast, and a shiny new Tray 94 board to top it off.
First off, I agree with the overall sentiment here that you can't go wrong with either of these brands. In fact a couple weeks before I bought the Axis I had a chance to try an Armstrong CF800 that belonged to a guy I met on the beach, and I was super stoked on that thing too.
Back to how much I love my new setup. This kit is just an absolute blast for my style and skill level. The 760 has great low end, and the small stab and short fuse make it nice and maneuverable. Yet it's still stable enough that even my sloppy foot changes are often successful. And I can pump it too, which came in handy when the wind was dying down near the end of yesterday's session.
As for the board, Axis sales guy (Evan) talked me into the short one when I was leaning towards the 110 or 125, and I'm glad he did. With such a big stable wing, I found I had so much more control and ability to stay up on foil through foot changes and jibes than I ever had on my old gear (2014 Lift 110). And while I do think the 94 has good bounce for its size, there's no denying that my old ~160cm Lift board was much more forgiving on the more nose-divey touchdowns. But I honestly see that forgiveness as a bad thing, at least for me. I'd heard people talk on here before about how very short boards "force you to get better" by not giving you the option to touch down. I thought it was BS, but now that I've ridden one, I'm fully in this camp -- at least for where I'm at with my skill level. If you're a total newbie, absolutely, get the big floaty board. Once you've tamed the bucking bronco and you're starting to figure out transitions, get rid of the crutch!
tl;dr: these are two great brands, I really don't think you can go wrong, and I'm head over heels in love with my Axis
