TrackerJacker is nice, but the person who wrote it is no longer on Roll 20, so you'd be somewhat on your own for support. TurnMarker1 is The (Mighty) Aaron's script, and is what I use. It plays well with GroupInitiative and has a nice look in the chat window. It just keeps track of who's turn it is (no condition tracking, as TrackerJacker and CombatTracker have) CombatTracker is Robin's script, and works well with his other script, StatusInfo, as well as The Aaron's TokenMod script. It has condition tracking (if you also install StatusInfo), as well as an optional timer. The chat formatting is simple, and the script is clean. I'm considering testing it out in my next session, and see what I and my players prefer. Any one is a good choice, though personally I'd use a script with an active Roll 20 member for support. The Aaron has helped me out of many an API jam in the past, and Robin has been receptive to input as well. My advice would be to try them both out in a test campaign and see which you like better.
