T47 is really useful for metal frames, because it allows for more clearance for wider spindles and cables to run through the bottom bracket. For carbon frames where the area between the cups isn't just a cylinder, the only real advantage of t47 over BSA it allows for the use of short spindle 30 mm cranksets, but that's a pretty minor benefit, especially since those don't seem to be in production anymore.
