The connecting security line for UA flights is pretty busy but there's 3 Premier Access lines which makes it easy for elite/C/F passengers. The RCC is a bit of a zoo though. Fortunately it's huge so you can at least find a place to sit.

My limited experiences at ATL (other than the fact I was flying DL) have been okay, it's not bad considering an airport of its size.
