Also, I don't see why one would prefer >>> over the standard function

With "." you have to read right-to-left to follow data's path.
For me that reading order isn't natural, and I imagine it is so for
most people which don't have a mathematical background.
Combined with >>= / >> you have multiple reading direction in the same
expression, as in
expression ( c . b . a ) `liftM` a1 >>= a2 >>= a3
reading order 6 5 4 1 2 3
So that could be one reason.
That's why I'm usually using =<< instead of >>= .
