I've got one of each. Orc Nb is good for more damage; Redguard Nb for better sustain. I play the Redguard more often in dungeons and the Orc is my main PvP character. There isn't all that much in it, unless you're looking at end game dps where the small percentages count, or the aesthetics. I love Orcs and if it wasn't for the great sustain (my Redguard is a WW and the sustain is very useful for that), they would both be Orcs
