I think in dry conditions, in the mountains, where wind is very common, Gore-Tex works. Otherwise no athlete would use it. It is not a bias, it just works. Also it does for daily use. I have an Arc'teryx shell, and it keeps me dry when it rains in the city. Yes, you may need to reapply the DWR once in a while, but it is not a big deal. It is a spray.
I don't use the shell often, because for light rain DWR is enough, you do not need Gore-Tex at all, so in 5 years I never had to reapply the DWR yet to my shell. I used the shell under heavy rain and snow, and it kept me warm and dry. That was in winter with multiple layers below, up to -10ºC.
In a rain forrest, there is nothing you can do. The humidity is so high that it is pointless using a rain jacket. It is ok to be soaked when there are 30ºC. But if you get soaked at -20ºC you die. So, it may not be the best product on the market anymore, but Gore-Tex is not a scam, not for winter shell jackets, at least.
