Motul 600 is a pretty good option. The only bad part is once it boil it you have to bleed it. SRF will come back and last a lot longer. Other than that, I've never noticed a difference.
From a cost standpoint, I'd go with Motul 600 if you do your own bleeding and SRF if you pay someone. I wanna say that I get twice the life out of SRF...so you come out even on the cost of the fluid but you save on paying someone to bleed your brakes.

Yes, keep it away from your oil...don't wanna make a mistake.
