I’ve used a number of waterproof golf shoes over the years, and I agree that if you otherwise like the look and comfort of a pair of shoes, the waterproofing is generally solid.
Some years ago, I decided to add these to my arsenal–Rocky Gore-Tex Socks–they make any golf shoe waterproof. I used them once on a really wet day at Royal Portrush in Northern Ireland and although my shoes were soaked by the end of the round, my feet were completely dry. Like a lot of Gore-Tex things, though, I don’t really recommend them once the temperature gets much above 75. Gore-Tex is breathable, but for me, it still retains an awful lot of body heat.
