Machamp moveset

The reason why it is better been discussed extensively here , long story short it is better and I have both
That said , sure don't use a TM on it you risk getting heavy slam , evolve anothwr. Mashop that would be my advise

I don't think I'd use the TM on that. It isn't a huge upgrade, and you have the potential to end up with steel.

CC deals 100 damage but needs a full bar to be charged. This means you have to deal more fast attacks to charge it up. Whereas DP can be used to deal a 90 damage faster. Yeah you lose 10 damage, but you can do a lot of destruction faster. Even better if you charge both, then you can do 180 damage faster.

Your 3C Machamp is still great, recommend saving your TM for something else.

Yeah, I would not use a TM for CC Machamp unless you had a ton of TMs and a ton of Machamps...

I suggest with move rebalances, it's good to have all moves and with tough raid bosses, multiple Machamps so just work on another...
