I predominantly right foot brake. For me it's a lot more comfortable and natural, and despite any benefit that left foot braking might give me, I'll always right foot brake.
That's not to say that I don't left foot brake of course, I right foot brake for 95% of my driving, but there are some corners that I'll bring the left foot in for, usually ones that only require a dab of brake to get the front turned etc. The best example I can think of is the Esses at Suzuka, where I bring in the left foot to keep the front tucked and have instant throttle. However I'll always right foot brake for everything else as it gives me the best feel especially in heavy braking zones. 👍
