Tried it a few years ago but went back to dBpoweramp as it does all I need and I like the way it integrates with the right click context menu giving you instant conversion options.
Might try Foobar again but…
It does everything apart from
mass album art downloader
specific things like sort by album art size
i use album art downloader and mp3tag for things like that
dbpoweramp is fine for the average user but foobar is more customisation in music management and in one single app, dbpoweramp has a couple and the batch options aren't as adjustable as foobar. When you drag your music to a playlist, you can then add columns to sort by that, ie add a replygain column and you can see what is replaygained or not. Convert single flac files/batch single track files, or complete albums cue files in one go etc. Different profile options ie
flac \artist\album\track - title
flac \artist\album\disc no- track - title
and create profile for vorbis and mp3
different library view options ie view by genre, artist, artist/album, by album artists (my dnla view so that helps track down to the specific one if that needs sorting)
