Suaromatia and LA TC have very solid PD with a mix of good archers and heavy cavalry. EA Aby is good, but since each point of PD gets you a single guy they really only shine one you get critical mass putting them not that far ahead (IMO) of nations who's PD really rocks at 20+ (ie. Mictlan). EA Aby PD of 10 is fairly meh.

I know its standard routine to bash monkey PD, but I find they work pretty decently in some conditions because of their large numbers, good defense, and lots of projectiles. Likewise, Caelum can be effective under some conditions because they fly forward to attack turn one. Neither of these are nearly as awful as Fomoria (my personal pick for worst PD) or Machaka.
