Totally different amps, which is why I don't really get why these two are your final options.

I'm guessing you're only going to use this at home or in the studio (otherwise the Carr would be a strange choice in my opinion), in which case I'd take the Carr.

At the price point of these amps, you probably also just want to go try them out for yourself or buy them from a place with a nice return policy should you not like it.
