I really just think it is a preference. For me, I don't like RA on the mic end. I find it easier to cinch the mic cables to the mic stand with a cable tie and still have the mics point directly forward and not sag in the shockmounts. Something about the spring effect that occurs with the loop of cable that comes out when using straight ends. When you have the cables coming straight down as with RA mic ends, you don't get that loop and spring effect, and I find it much harder to not have the back of the mics pulled down in the shock, making the front of the mic point up.
And having put together many mic trees, I don't like RA's much when it comes to clamping. The right angles and the cables coming straight down make it much harder to pack in a lot of mics on one stand. Getting 2-3 pairs of full bodied mics using RA cables packed onto a stand with another 3-4 active sets is much harder than putting up full-bodied mics with straight connectors.
