ZEROZEROZERO Been using iCab since it was a puppy and now at 4.01 it's still the best utility browser: FAST, full of features, stable, and did I mention fast?
I really appreciate the error report, the best favorites toolbar, and all the tools: filter manager, cookie manager, forms manager, offline mode, download manager... live update of offline files (for coding websites) autosave session... yada, yada, yada. And it rips webpages to five different formats.
Yes, there are some issues, but the tweaks and fixes come constantly. Best thing about it IMHO: it is not free (unless you forego a few minor features) - by that I mean it doesn't come with any strings attached.
Great browser, great developer support, best money I've spent on software.
