I think that for most folks battery powered will be more than adequate to get the job done, and they will be more convenient.

I used to have a compressor. I rarely used it because it was loud and a pain compared to not using it.

If you're going to get a compressor, get the quietest compressor that you can find.
If you're going to get a compressor, make sure that the compressor/motor will provide enough air for everything that you need to do.
If you're going to get a compressor, get one with a big enough tank to do everything that you may do.
