I've found Carrara's render to be pretty stable. I've put it through an 8,000 by 8,000 pixel render and it handled it. Also, people have pushed the latest version C5 with thousands of polygon modelled trees (each tree can be upwards of 10,000 polygons) without Carrara croaking, although it can take alot of time depending on settings, but that's true with any app. I think you'll be happy with it and C5 supports Poser figures natively yet also includes TransPoser 2 to give you access to Poser's Dynamic hair and clothes.
