I'm a Purex F&C fan. We use primarily prefolds and covers. However, I do use BG 3.0's for night time and I also use some AIO's for out and about. I wash all of the above in Purex and haven't had a problem. I use about a quarter to half the recommended amount. With our hard water I also use some Calgon water softener about every other wash. I've had to strip a few times, but nothing major and more than likely due to our water.
I think detergent performance is heavily based on water, so give it a try and see if it works for you, Purex is pretty cheap.
