I feed PMR... LOVE IT! Before going PMR I tried to feed my cat (before I had any of the pups) pre-made but he refused it. So I don't have any experience...many members here feed pre-made and will pipe in soon.
If you have any questions on PMR when you're ready, just let me know.
BTW, if your pup has runny poo and throws up on PMR...it's the owner who is doing something wrong...i.e, not feeding enough bone.
