All in all it is a very capable steel. You would really have to examine every steel property individually to pull apart how it stack up against other steels, but bottom line is that it has no real weaknesses (talking about stainless steels only). It takes a good edge, but is not as abrasion resistant as VG-10 let alone S30V. Edgestability is good, meaning you can thin out the edge quite a bit without getting a nasty surprise. If you are talking about the Byrd series, the 8C13MoV is somewhat unique as it is run a roughly a point harder than comparable steels, which probably shows up in the edgestability.
Given the choice, I would prefer S30V, VG-10, ZDP-189, but I wouldn't be (or given that I own a knife with it: I am not) unhappy with it (and yes, I am somewhat of a steel snob). Considering the price of the knifes that this steel is usually found in, it is really excellent stuff. IMHO, much, much better than low grade stainless steels like the 420 series.
