Why people say Dynamic punch better than Close combat?

I was wondering the same.
The only reason I can think of is:
1 bar move needs more time (double?) to be fully charged than 2 bar harge move.

Yesterday I evolved 2 machop into Machamp and got one with Counter/DynPunch.
I'm still holding on to power him up, but I want to try it against Blissey asap.

They are fools or liars. DP is obvs better.

DPS is not a good estimation of one move's power. They shoudn't show it anymore, it's confusing.

DP does 180 damage in 5,4sec for 100 energy
CC does 100 damage in 2,3sec for 100 energy

Within the 3,1sec gain from CC faster Cool Down you can use 3 Counter which is 30 damage + 24 energy (let's consider this as 24 damage since CC does 1damage per energy)

So in one full cycle with DP, you make 26 damage more than with CC. Its not a hug difference but DP is a little bit better.

Two bar moves seem more valuable now because all quick moves were slowed down meaning that it takes longer to charge.
