I have both Poser (7 and Pro) and Carrara.  I have tried, but given up with dynamic hair in poser.  I use it all the time in Carrara.  It's as easy to use as conformed (prop) hair if you don't animate it, and it's still lifelike without animation (although if you want it to drape or blow, you have to animate).
