I use PV/PM because it was the first one I found that made it easy to digitize my vinyl AND sounded good. Others may be equal today, although I'd be surprised if any were better. Unfortunately, PV has the ability to create bookmarks in iTunes which point to locations in the album file and saves a lot of disk space over creating an album file and then creating music tracks from that, but it locks you in. Consequently, unless I want to create music tracks, which would take a very long time, I will be sticking with it.
I just discovered it has a bug that may be important to some. It cannot downsample and play bookmarked tracks. Downsampling can only be done from tracks that are on the disk. This is only an issue if you create high-res files, bookmark them and later decide you need lower resolution for some reason.
