The most elegant interface and greatest prefs.
But it is TOO CPU consuming and slow to load (the program, not the pages).
It's a CPU eater, I can't even messages without having to wait in forums etc. And I can type messages just right in Mozilla, Firefox Safari, even IE.

I really tried to love it.

But have you seen Shiira? Still a little buggy, but blazing fast, uses the same engine but is somehow MUCH faster in rendering than Omniweb or Safari or even Firefox.
