Believe it or not RBF600 actually has a higher boiling point both wet and dry vs AP 5.1. AP 5.1 is excellent performance for the money though, so it is a good fluid to use and a fair bit cheaper.
RBF600 Dry: 594F
RBF600 Wet: 421F
AP 5.1 Dry: 516F
AP 5.1 Wet: 369F
Note this is just the manufacturers specifications, I haven't seen any 3rd party test results to back up the individual manufacturer claims.
