Have experienced the good, the bad and the ugly with rain gear.  Purchased a paddling jacket last year from NRS that is absolutely waterproof, and it is an anorak with just a half front zipper.  Perfectly dry, and a pain in the butt to pull off over the head.  My best full zip jacket option currently is a Patagonia that also works well, not as good as the anorak for waterproof.

I've had a couple of pairs of Marmot Precip pants.  They start out OK, but loose their waterproof fast, and really don't work in a downpour.  They do have full side zips that are very convenient.  I have to be picky, because I wear a medium long pant, which is hard to find.  Recently purchased a pair of Arcteryx pants that were expensive, and worth it.  Highly waterproof and breathable, with a drawstring waist and short side zips at the ankle.  Very lightweight.  Downside is no pockets.  My 2 cents worth.
