Animal companionL Rhino or Ceratosaurus?

[Abraham Z]

No opinions about which AnC is better but 2 notes: 1) Narrow Frame won't affect the size of your charge lane: it still needs to be 10' wide. 2) I've found that Power Attack is less desirable for an AnC, even a high STR one, than I would have expected. The reason is that their BAB lags significantly, so the to-hit penalty of PA is felt even more strongly. And lots of bonus damage doesn't help when you miss.
