Protracker was Soundtracker honed over literally years of versions. It was very streamlined, sensible, and solid. Definitely the best tracker at the time. The problem I have with newer trackers is the complexity. They don't seem to be designed very well. However, if you've never used a tracker before, Protracker may be a bit hard because of all the keyboard shortcuts.Consequently, other trackers maybe preferable. Couldn't tell you which though. I haven't done much tracker stuff for years.
