Could you explain what you mean by "quirky"? For me, aside from a few pages that render more accurately in 5.8 because of the updated WebKit, it's not very different than 5.7.

My guess is that most of the changes I'd like to see — for instance (I'm hoping here) inline find a la Safari and Firefox — aren't likely to show up until the version 6 betas. I don't think we'll get much of a sense of the future of OmniWeb until then.
