I'm a suspension nerd. CSC, Champion, Motor Trike, all use some variation of double a-arms, the hot setup for most all race cars these days. Roadsmith and Hannigan use some variation on trailing arms. Stone Age technology, but implementation is key, and both get some excellent reviews. DFT is in between, a lower a-arm with the driveshaft serving as the upper a-arm. It's a setup that was used on XKE Jaguars and early Vettes.
A key spec that, as far as I know, NO ONE publishes is wheel travel. More wheel travel generally means a better ride.
I went DFT. Their workmanship appears to be excellent. In spite of the fact that they don't extend the wheelbase, the ride is reported to be at least as good as any, probably due to long wheel travel, they modify the mufflers to get it. I'd think it would be more difficult to get that with double a-arms, but, as I said, the data is just not available. The clever design uses the stock swingarm, driveshaft, rear gears, and brake. These (especially the driveshaft) are areas that have been problematic on some trikes. I also liked the non-extended wheelbase, and plain body, that doesn't scream "look at me" like most trikes. Finally, I wanted IRS and to self install, which limited me to either Roadsmith or DFT. Maybe Champion, but I didn't want that brand.
DFT has as many fanatical owners as any (actually they sell most of their kits to Harley guys). But you pay close to $2000 more than a Roadsmith. Worth it? Who knows?
Bottom line. You probably could make your decision on the basis of installer quality, and be happy. If you can visit a few dealers and test ride a bunch, that might help. Or maybe not, riding a trike at first is... strange.
