I don't know Bad Rats enough, so I might go with Sonic Bum.
Though it's history is tragic, evidently supposed to be a reimagining of the Sonic franchise that went to... well, how it is due to SoJ insisting on it and blah blah blah. It wasn't supposed to be a bad game, but well, the same thing that happened to '06 cursed Boom.
I vote Sonic Boom.
