There are three things I love about this jacket -- the hood, the packability and the thumb straps! It also has a little window to see your watch when you're wearing it [I haven't really needed to use it yet].
The sleeves are a bit shorter than I'd like to see in a rain jacket but I do have really long arms. When I'm just running + have waterproof gloves on the sleeves are fine, but I often wear this jacket on my bike when my arms are stretched out...they aren't quite long enough to keep my wrists dry when reaching for the handle bars.
Most importantly...this jacket has kept me DRY!
