I have cages with drop down doors, swing out, glass sliding, and plastic sliding. For me, feeding is not an issue with either of them.
The only doors I dislike are the plastic sliding doors for large snakes. I’ve had two different snakes bow them out and escape and one totally blew the doors and tracks out.
Cleaning is easier with the swing out and drop down. But overall, I like the nice solid beefy feeling of glass sliding doors which make them my preference.
