This may not be all that helpful, I've tried both and liked both (Fim 880(G)* & Oyaide R1). I don't think you can go wrong with either one. Currently have 2 of each in my system.
PS: R1 may have an edge in build quality but costs more as well.
*880 comes in several versions, (G) is gold plated version.
