Why was it alike?
Sanji DJ attacked > Doflamingo blocked > Sanji DJ attacked (named attack) > Doflamingo dodged pretty easy > Doflamingo atacked > Sanji noticed something > got hit > Sanji recovers > Sanji attacked double DJ (Named attack) > Doflamingo blocked with his coat (most likely Armament Haki) > Doflamingo froze Sanji's movements > overheat > Law interfere
Zoro runs toward Doflamingo > Isso interfere > Isso use gravity > Zoro falls down the hole > Zoro overcome gravity > Air slash > Isso steps back
(1) Doflamingo was toying with Sanji while Sanji was desperate trying to hit Doflamingo, Sanji lost his fight
(2) Isso blocked and apply heavy weight to Zoro and Zoro got back up and running making the guy step back due to the air slash while overcoming his gravity
(3) Both make a similar comment - similar
Not quite Sanji got praised by DD.. Zoro got praised by an Admiral. Further Sanji needed to be saved in order to live. Realistically we don't know if Zoro would need to be saved as well only time will tell what I find odd is the fact that Sanji didn't explain to Luffy Doffy's fruit.
