Fighting has a lot of really good types, like no guard machamp, conkledurr, the hitmons, infernape, and many more. they also tend to have very good stat spreads, rather than lots of jack of all trades master of none, if that makes sense. And again it hits a lot of types for SE or neutral.
Oh and both resist SR.
