I actually dont think that General Kreat offers much as a commander, but shell go great in the 99 of decks such as Krenko, Mob Boss or Purphoros, God of the Forge that are already looking to throw massive amounts of tokens onto the battlefield to finish off opponents
Eventually we got Breya, Etherium Shaper, the best Artifact commander ever printed, but still a portion of the community was unsatisfied because Breya has W/B in it and they didn't like that - despite the fact that you can build her with zero White or Black cards because extra color options is bad or something I really don't know
Just don't be surprised if squirrels, lizards, frogs, bats, or raccoons steal the show since lots of archetypes are predictable, and work great together
