When I needed to upgrade to foul weather gear suitable for offshore work in cold weather, I asked a good number of sailing buddies what they recommended. To a man, they all recommended the brand that they had bought. Not a single one felt that they had made a bad decision. And the list covered just about all of the well-known brands.
What that says is that all the major brands are great, or maybe it says something about human psychology, I'm not sure which.
BTW, I like my Gill foulies.
