I really really like Pfau's pellets. I have been breeding and raising rabbits for 10 years, and so far they are the best. I used to feed Purina, and switched to Show formula for awhile, but my rabbits were extremely unhealthy and their coat condition was terrible. I'm about to try a suggestion from another breeder of incorporating some Fiber 3 into my Pfau's pellets to lower the protein, If I find anything good from that I'll let you know. I looked up Oxbow today, and it's the biggest pile of crap I've ever seen. It's extremely low in protein (Only 12%) Rabbits need 14-16% to stay healthy. It's also ridiculously expensive. My personal (And rather pessimistic, I apologize) opinion is that Oxbow is a hoax to sell poor quality food to the ignorant for loads of money.
