I like Sonique better than Winamp, period. Winamp's EQ may be better if you like bassy music, I suppose.. it has adjustments that go lower in frequency. But only 10 adjustments.
However, Sonique's EQ is much more extensive, with 20 levels. Plus- and I guess this is Sonique's biggest claim to fame, it's MP3 decoding engine sounds better. I definately find this to be true. Someone from the forums told me to get Winamp3 yesterday, and I sat and listened to the same song over and over with both.. Not only does Sonique sound better to me @ default, I can make it sound even better to me by adjusting the EQ in ways that Winamp's can't.
Plus, I like Sonique's Pitch feature. I realize Winamp has plugins that do this, but they just don't seem the same to me.. Sonique's implimentation of it is flawless.
