FAB powder is available around here in quite a few places. One of our stores (Bi-Lo) has three of the four scents in powder and liquid. It's true, the powders don't dissolve immediately. I noticed that this past winter in one of my machines with a recirc. filter, as I could see and feel the specks in the water. It took about 5 minutes for it all to dissolve.
The Fab from Phoenix Brands is still very low sudsing, at least in my experience. Even in a Kenmore with the straight-vane agitator (which can make hardened cement foam up) the detergent doesn't suds. I like that. The scent is nice to, but I never used the C-P version to compare the difference. No complaints on the current stuff. I do have one new box of the C-P product, which I will open soon and try.
