It's hard for me to say, I'm pretty sure Joshua would have knocked him down again, but then again I was pretty sure he was going to stop him in the 5th. But I feel like Wlad was done, and if the ref didn't stop it he would have taken unnecessary punishment.
He was most likely going to win with those 2 KDs but Klitschko deserved a chance to survive the round. Just pisses me off when refs that are supposed to be professional and are right next to the action don't notice how Klitschko isn't really getting hit.
I'm usually the first to complain about an early stoppage, and he really didn't land much in the final flurry, but I think Wlad was finished and could have been really hurt so I can't really complain about the stoppage
Wlad showed no complaining, stated best man won, both leaving the ring with brains intact, they put on a good fight, thats enough for me.
