The Motul RBF600 works quite well. I recommend to our customers to alternate between it and ATE Super Blue, as they have nearly identical specs wet and dry, and the color change makes it very easy to bleed. For 90% of people out there, either of these work well. The ATE is a terrific value, where at least here in the US you get 2 x the amount for about 1/2 the cost of Motul.
The Castrol that many run with success is the SRF. I've used it, works fantastically well for an all out track assault. Overkill for just a street car, or even a track day car on anything but full r copounds and an aggressive driver, and it's very expensive. The Endless Fluid (called "RF-650" I believe even outspecs the Castrol, and is used by many motorsport teams worldwide, and was used by Honda in their F1 program, as well as by Porsche in the GT3 Cup cars (comes standard from Porsche that way).
