I started with Aperture, but soon switched to Lightroom. It ran much faster for me, and I got on with the library system a lot better. No virtual copies or anything hogging disk space either.
A lot has probably changed in the last few years though.
FWIW I cannot get on with CaptureOne, it doesn't seem to have anywhere near the facilities for cataloging, sorting, etc that the others do. Least not last time I used it.
