Alright, here is another subjective list that is based upon my personal experience. I know the OP did not want an explanation for each, but too bad.
In no particular order.
Groove - there are good Grooves out there, but they are hard to find. The only really good thing going for the Groove right now is that they are coming in new, poppier colors than other Champion discs.
Beast - great for lower powered players, but anyone who can get a hold of a drive cannot throw these. It has a light switch where if you suddenly exceed its intended speed it becomes fliptastic. There is no gradual exceeding of this speed; it just happens.
Wahoo - It was supposed to be what 140g and under Bliazzards are, a controllable distance driver that takes the fear of water away. It is hard to describe its flight because something about it just never seems right.
R-Pro Boss - this version of the Boss is so completely different from all other discs in this mold that cost me several throws during a tournament once. It is a flipping machine when you expect a high power drive with a moderate fade. Also, despite it being an open grassy field, I still managed to take a chunk out of it.
Pulse - my lighter one was like the XXX, but my heavier one was incredibly understable. The only good thing about the Pulse, it will fly straight if you have massive OAT issues (at least the overstable ones).
Blizzard Wraith - This is a Wraith? Funny, flies like an SL, another super sensitive disc that I cannot throw harder than 50 percent.
TeeDevil - I imagine an old woman yelling out, "where's the glide?" When there is a puff of wind, the glide appears but only because it is turning over and trying its hardest to fly as far to the right as possible, especially when I do not want it to.
Wolf - Others have already covered this.
First Run ESP Nuke - I clipped a tree. When I picked it up there was a twig sticking through the flight plate. A nose sensitive tree magnet that can get pierced easier than a Goth teenager.
Any Discraft putter in D or Soft X in recent (last two years) runs - throw these discs for more than a week and they are gouged, warped, and or chunked up. You cannot use these discs for anything but putting because of this.
Any Innova putter in Champion or Star - while true of any putter in premium plastic, it seems more so in Innova. They are seemingly coated in grease when it comes to hitting the chains; they knife through with no effort whatsoever. I think they are okay for approaches and driving because they can take the abuse of hitting trees and things on the ground, but they just cannot hold the chains. In both cases, with the Discraft and Innova putters, you essentially need to carry two or more putters to keep them fresh.
