I have compared the Duotone Aero glide 725 with the Mikes Lab 700 with gates and the AFS 700 Pure v2.
I have been riding the mikes lab and duotone for quite a while so I am probably biased that way.
Having said that, I found the AFS Pure V2 to be the fastest foil. The ML and AFS are very similar in the feeling on the turn in waves. Not really too many differences.
Overall I would probably go for the AFS since I can switch to the swept tail for pumping. I also like being able to shim. Also having the uhm mast means I could put the silk 850 on arguably the best mast on the market (11.8mm and super stiff).
A friend just hit 27 knots on the afs pure 900 so I am excited to see how fast the 700 goes. Having been designed by a leading international moth foil designer I imagine it could go as fast as 30 knots in the right hands. I went 25 knots without trying on a wave session at Daymer Bay.
It was really easy and accessable for beginniers as well but with pro level performance.
