Role Master 2d Ed. wasn't bad, my friends and I loved playing it (and even the 1st Ed. way back in the day) until we went back to MERP and then HARP, but we got overwelmed by the beast that was RMSS. We never played RMFRP, so I don't know anything about it.
Just remember to HARP on my friends!
Overall, I have been very happy with ICE's products and I would like to have seen them higher up on the list.
