yWriter vs Scrivener

Anyone here have thoughts on yWriter vs Scrivener?

I like the way yWriter functions. The UI seems a lot more intuitive. (this is after roughly an hour of playing with both tools.) I like the way characters and places are stored and how they are related to the sections.

Scrivener seems slightly less intuitive, but I really like that you can send a file right to epub or mobi format.

Any feedback you have about one or the other or both is greatly appreciated!
