I think the majority of users on this board use WKO+.
Honestly, I doubt that there's much difference in the actual information that's being provided to you. The presentation might be different, but I think that's where the line is.
If you want to try something free, then you can try sporttracks for a bit while you explore the differences between the other two programs.
In addition, you can do the WKO+ 2 week trial to see how you like the program now that you know how raceday works.
