Having lived in Oregon, Washington and SE Alaska, I've tried most raingear out there. If it's really raining, the rubber/pvc coated stuff, like Helly Hansen or Grundens, is water tight and keeps you "dry", but it's bulky and noisy and if you're hiking it keeps the sweat in. I have Gore-tex jacket and pants for hunting in and it has been a life saver on several occasions, though I don't like wearing it all the time if I can help it. One thing to keep in mind is that if your raingear is keeping the rain out, it is also keeping your sweat in, even the so-called breathable stuff. You have to decide how wet you can stand being, wearing raingear, you are typically damp and not wet. I've heard the Frogg Toggs raingear is pretty good, light weight and keeps you fairly dry, though I've not tried it myself. A cheap option is to take a garbage bag, cut holes for your head and arms and wear it under a wool or fleece sweater/shirt.
