Depends what style you like, really. Smocks feel more like shirts, jackets feel like coats.
I've got the jacket - I always prefer the full length zip so that you can get it on and off quickly. The extra weight isn't really an issue.
Very good to run in - I'll have it with me when I come to the L50, although I hope it'll stay in the pack rather than have to wear it! Unlikely!! Completely waterproof but very rather than extremely breathable. Stretches, and above all doesn't rustle.
I've also got the Cypher jacket but that does feel like a coat and only use it for walking. That one is extremely breathable. A very fine garment indeed.
