Theres a few factors like potential system upgrades and leader skills you have to consider.

If you dont have the proper leader youre not gonna get the most out of your cards.

and if youre watching people on youtube dont forget they put more money into the game and they probably have maxed out cards (via special attack and potential system upgrades)

To get the most out of those 2 units you need either:  A Super Leader - Potara Leader

Theres other teams they fit on, but if youre running a team with both thats your best bet.
