I got a Simms. Doesn't cook you when it's hot, and you can always get warmer using layers under it.
I've been in some super heavy downpours that I had no business being on the water in, they snuck up on me. Even had hail mixed in one of them. Man, that stuff hurts the ol' noggin.
Anyway, I never plan on a different brand. I don't see how it could be any better.
