I can back in better than I can go in, simply because I was taught to use my side mirrors and the two white lines as guide. I’m more accurate because I can see more and don’t have my view blocked by the bonnet. The only downside is that judging the distance behind you is a bit awkward.
Also, it’s safer when going out.
In the U.K, it’s one of the few moves that new drivers may be asked to be tested on, like reversing around a corner and parallel parking.
My girlfriend is opposite, as she can drive in better than I, but she is useless reversing in.
