What’s the difference between Smosh Mouth and Smosh Alike?

I’ve been getting into Smosh recently and keep seeing both Smosh Mouth and Smosh Alike. They seem kind of similar, but I’m not sure what makes them different. I mean they do have similar podcast style videos and a more longer format than their other channels and i know that smosh alike used to be Anthony’s channel. (Sorry if I’m asking a dumb question :<) so can anyone tell me what makes them different
