Had a Signature 1950r
Now have a BC 670HT
Spent many hundreds of hours in each.
I think that they ride almost the same. The 1950r was quieter in the chop but landed harder in the big stuff. The BC feels bullet proof so I treat it a lot worse.
Main benefit for me is that I can clean the BC out with a fire hose and a scouring pad. The 1950r required soft brooms and careful hosing.
Each to their own, but I know that I wont have to replace the rotted floor in my BC anytime soon.
