I bought my black two-piece in the spring of 1997. Since then it's accumulated a lot of miles--how many, I'm not certain, but when black fabric fades noticeably, it's a lot of 'em.
In general it's held up well. True, most of the zipper pulls have fallen off, but paper clips or key rings replace them easily enough. The fabric's getting a bit frayed in places, and the Ultrasuede collar's looking a bit sad, but otherwise the material's holding up well.
I've found the suit to be waterproof, to the point where I don't even own a conventional rainsuit--provided I remember to give it a once-a-year treatment with the "TX Direct" DWR stuff. One rain-related peculiarity I've found, though: if you've got a US-style sidecar (mounted on the right), you may find the bow wave of the hack lifting the rain flap on the RC jacket and forcing water in.
One of the problems I have faced is that because the suit's so durable (and expensive), I've had to find a way to deal with my inevitable weight gain. Here's the trick I used: sew a second zipper-half on the end of the rain flap. This will zip to the matching half of the existing zipper, and give an extra 1.5 inches of gut room. And no, it doesn't seem to compromise watertightness.
The suit is perfect for touring, especially on a sporty bike with limited cargo space. I often take off with only shorts and t-shirts in the saddlebags, and just wear the suit over 'em when I'm riding. And when I get to a hiking trail, a few seconds to get the suit off and I'm properly dressed for a walk in the woods--something you just can't do with jeans and leather jackets!
I'll cheerfully confess that I haven't crash-tested the suit, and don't plan to. In all fairness, I didn't buy the suit for crash protection, though that's a nice bonus. It's just a really convenient thing to wear while riding. (Posted on 2/21/10)
I have had this suit for 16 years now, and absolutely love it! It is very comfortable, does everything. It is so easy to put on, there is never an excuse for not wearing it even on short trips. For touring, it is great; lots of pockets, good ventilation. I don't have to carry a jacket; if it is cool, I can unzip the jacket and wear it while not riding. Waterproof, pockets where you want them, great protection, and after 16 years obviously very durable; very hard to beat. I purchased a Darien suit a while back, and hardly ever wear it; I like this suit much better. I'll be getting another Aerostich when this one finally gets hung up for the last time.

I bought the two-piece but if I had it to do over again I might get a Darien instead.
First off these are great suits and very durable, the two piece can come in handy it just depends on how you use it.
If you plan to constantly be zipping and unzipping the jacket and pants together you may be disappointed, it isn't that simple as lining everything up and getting it to zip takes time. It does work well for some situations, for istance if you are commuting everyday you can zip it together and take it all off at once, then when you go on a pleasure ride you can unzip the pants and jacket so you can just take off the jacket as needed.
The other comment I will make is that it is not just as easy as the one-piece when zipped together, there are two separate zippers one for pants and one for jacket. Whereas the one-piece just has one zipper that goes all the way from top to bottom. So not quite as easy but pretty close.
If you really need a two-piece and don't expect to need to zip it all together very often I would recommend going with the Darien. If you are rather uncommon size like me, large shoulders but smaller waist, the Roadcrafter when zipped together will fit a little strange due to the larger jacket zipper not quite matching the smaller waist one... looks like I am pregnant.
