I've been using Sketch exclusively for the better part of a year, and it's not just a better tool for designing web and mobile UIs, it's a real pleasure to use.

There are still quite a few bugs, but even with those, the Sketch workflow trumps Photoshop, Illustrator and Fireworks. Version 3 should also address most of these, and is supposed to include support for symbols as well.
