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.
