He's a more dangerous one. Brandao has decent takedowns and a good submission game. Cole wouldn't have gotten the takedown ever most likely.
I think this one could end up looking very one-sided, but Brandao does have higher chances than Cole of forcing a takedown and snagging a sub early. We haven't seen Conor on his back in years (and he wasn't good there). However, if Brandao doesn't get it down fast, or just opts to brawl, he will gas and wind up a punching bag.
