1: reversal (dektol mostly)
3: c-41 (powder kits)
I use reversal for anything I want to keep, or for more seriousious work. XTol for everything else, but I am actively looking for a replacement. I just can't come close to using it up before it dies on me. I probably will go Thornton 2 bath or some pyro I can make from scratch, when I need it.
