I am not expert enough to knowledgeably comment on this, but I will anyway.

I started foiling under my kite back when Carafino was the only marketed option and this was considered freakish. Foiling took off when the racing community adopted it, using highly refined carbon rocket ships for maximum speed. Liquid Force released the first "fun" foil: cheaper aluminum mast/fuselage, low aspect, slow and easy. The kite foil world divided, as anything that wasn't a race foil was considered a POS that didn't work ... and then there was everyone else, showing that "fun" foiling could be achieved by literally taking an angle grinder to garbage plywood. Since then, the mainstream has taken over and freeride fun foiling, where turning and lower stall speeds are emphasized over speed, is by far dominating.
I see it pretty similar in the surf/sup foil community. My first was the Takuma V100 clone, at the time considered the biggest and easiest wing on the market. At 1200cm2 it is now medium size and while it's really easy to lift, it's someewhat extreme shovel shape makes it not optimal for faster gliding. But along with Naish, it was the only option that wasn't GoFoil $$$$. Now the market is inundated with mid-quality mid-price options, and from what I can see, they are all functionally adequate. The market seems to have matured and the styles that work seem somewhat standard. That's not to say there isn't annual innovation in product line: gull wings, steps, winglets, etc ... all ways to differentiate from the competition. But call me cynical, a lot of it seems like the fishing lure business: all the variations in colours and shapes are designed to catch fishermen not fish ... the commercial guys use the same old bi-color spoons that their grandfathers used....because they are simple and they work.
I expect a flood of responses that _____ is by far the best and maybe the only good option ... but I find most people invest themselves in the gear they have, master it, and then when they demo something different it feels weird and don't like it as much. So getting useful user reviews is tough. I am open to whatever, but I am currently on Slingshot ... stumbled into a package, works great, but most of all I really appreciate their dedicated interchangeability. One fuselage, one mast, works with all wings, from kite through to downwinding.
