I'm super new to BMX in general so I don't have a lot of exposure. I bought a Fit PRK and it seems to be a pretty serviceable bike. The only issue is most of the frame is hi-ten. The top and down tubes are chromoly, though. I do have some concerns about breaking it on big drops.
As for subrosa, I can't speak for their bikes but I have their lights, gloves, shoe inserts, and invisalite shin/knee pads. The lights arrived damaged and the gloves ripped quickly (but I was able to stitch them up... diy or die). I wrote them about the busted lights and gloves and received no response so your mileage may vary. I think their frames look very cool but I'd hesitate to buy one after that experience. They did toss a neat little coin purse in with my order though...
What I've seen a lot out and about is Sunday, Standard, and Cult, for whatever that's worth.
