I'd say krogan over yahg in hand-to-hand combat. The yahg are bigger and look like they could hit pretty hard, but krogans are just too difficult to kill. (Recall Thane's preferred kill methods for krogan in his Shadow Broker dossier? All those redundant vital systems make assassinating them a real chore.)  The krogan would be pretty beat-up at the end, but I just can't see one losing in hand-to-hand against anything with a less ... durable physiology.
