I had Suunto Wing and as soon as Suunto Aqua came, I sold my Wing and got the Aquas. I know you only asked between Sonic and wing, but I’d recommend Suunto Aqua 😉 if you swim no brainer, even if you don’t swim my opinion is Aquas are the best of the three, offline music, water proof, + some other features like neck fatigue measurement, neck mobility measurement and jump test assessment.
