I had some tracks that EA just sounded horrible on, before quantizing, just having it active made the cymbals choppy. Tempo was like 210, skater punk stuff, so I bought Music Production Toolkit 2, and I'll probably do everything with Beat Detective now.
I prefer EA for the workflow, but BD sounds way better. BD also is a pain in the ass because of all the fade files, some songs have over 10,000 fade files and region edits, the PC starts to get really slow 3/4 through the song.
If I got 10K RPM drives it might not be so bad.
BD is a pain in the ass, not fun, but sounds better.
