copper is the best way to go in my opinion. proven track record, pex is still relatively new. The guy with the corrosive water, if it was/is that corrosive that it will eat the walls out of copper tubing and you have city water, you may want to get with your neighbors and file a class action lawsuit against your local water department. If the chlorine in your water will eat copper 1/2 the country is going to need repairs. Copper isn't schedule 40, type M has the red lettering, type L has the blue lettering, and type K has green. Most houses have type M. Pex is the cheaper way to go no doubt, but remember the old saying of you get what you pay for.
I recently had to replace the old galvanized pipes in my house. My plumber eft it up to me wether to use copper or pex. I went with copper for a majority of it, but something I used Pex because it was easier to snake the pex through the walls so. everyone said it was a personal preference, and that they both are good choices. Pex is cheaper, but the tools to install it are quite expensive and some plumbers are not familiar with it. Copper is very expensive, but any plumber can install it and the installation will be less.
