Wrex has lived a thousand years of combat ranging from mercenary work to war not to mention fighting the Reapers. He easily out matches HK's four years of assassinations. This is one X-factor that is not close to being even.

Not to mention that that argument really doesn't hold up. :/ If you argument is that Wrex only has had worthwhile experience as of late then That is the same as HK who has only existed as of late.
