I have only used Arccos, This will be my 3rd year using it.
It gave me the stat tracking I was looking for and also uses the stats to show you what your positives and negatives are in your game. This can be used for each round or over several rounds in the app and the website. If you want the best experience it is worth getting the Link it works much better than phone in your pocket, but it is one more thing that you have to keep charged to be able to take advantage.
I know having Arccos has made me want to play more golf because it gives me instant feedback at the end of the round if I've improved on what I have been working on in practice.
I wouldn't recommend if you don't like going back and check you round, at its best it usually needs 3-5 corrections a round ( which I do while playing) but for me this is much easier than filling out a scorecard with all the stats I wanted to track.
