My old bottles tasted nasty after just a few hours. Camelbak bottles, even the plain, uninsulated ones, have zero plastic taste even after the water sits for a couple of days. And the valve works great. I've had the same ones for 6 or 7 years now.
The worst thing is those 5 gallon "igloo" style water dispenser jugs at event ride rest stops. If they filled and cooled them overnight, it's a very strong plastic taste. Yuck.
