My understanding is on big/dangerous game the pro's prefer a controlled feed because of reliability. Maybe today that's not as much of the case as it was back int he day, but that's still how I view it.

Controlled feed will always load, always shoot....might not be MOA accurate, but at 50yds, what's that matter to a charging animal?

Push feed I think of like a remington action, accurate.

Maybe that's an older view, and I'm sure some guns can be controlled and very accurate, as well as some push feeds can be less accurate.

I believe I read its easier to make a push feed accurate, than it is a controlled feed.

Controlled should be quieter to chamber/throw a round.
