Check out Tyler Freel's podcast on an epic failure of $1200 gortext rain gear.

The basic problem is gortex may work 99% of the time, but when you really, really need it to perform,
it may fail (windy storms).
Listened to the whole thing... I don't disagree... but I'm also kinda like...
I've posted on probably a dozen threads about rain gear and I also advocate for buying for your specific use.
If you need something for super heavy rain rubberized gear is always the way to go.
Tyler complains about the cost/ performance, the price point comes from the fact that the high-end gore-tex gear is light weight, durable, and breathable not that it is the ultimate waterproof fabric. It's the best waterproof fabric that is light weight and also breathable.
Sitka stormfront is marketed for his use case, so I definitely think he has a valid bone to pick there.
Personally I've hiked in that kind of weather twice, once in Scotland and once in Iceland. In Scotland it was so windy a one point my wife and I though we were going to get blow off a cliff because the wind push us off the trail on accross a flat but grassy field towards the edge of a cliff. Go lay down on a soccer field and imagine how windy it has to be to move you.
Anyway, on that hike my Sitka downpour, and my wifes mountain harware jacket totally failed... both gortex. Same water in your pockets kinda thing.
Similar day in Iceland... my arcteryx jacket held up great... I got wet at my neck, and cuffs from rain blowing in, but was otherwise draw after a 4 hour or so soaking. I think I would have experienced the same thing with rubber gear.
IMHO sitka is good, but it is not the best gore-tex gear on the market. There is a massive difference between the Arc'teryx Alpha SV and the sitka stormfront jackets.
Is all gore-tex crap and totally not worth it for the money, no... it just depends on what you are looking for an how you are going to use it. I have 4 different rain jackets, they are all good for different use cases.
