Centaur good, ogre good, ogretaur disappointingly bad.
9 aberration RHD simply cripple this thing. It's got okay-ish natural weapons that it can use with manufactured ones, as well as passable strength and constitution scores, but in the end this is just another RHD-inflated brute. Deafening Bellow, its sole unique trait, is weak bordering on useless (reminder: any potential target is also in charge range): the developers should've made it a swift/free action to encourage some use at least.
A disappointing -0 LA overall. With like... four or five hit dice trimmed this might've been a decent playable monster.
