I play pickleball and often times transition the paddle to my left hand where I wear my watch. For this reason I want a band that will hold the watch firm, but not overly tight. I don't want the watch flopping around while lining up a shot. So, I prefer bands with infinite adjustment or a solo loop that holds the watch snug. I don't do well playing sports with bands that use holes for adjustments. They end up too loose or too snug.
So, I prefer the Apple Solo Loops. These can deal with sweat, and when sized properly, they hold snug without being too tight. Bands like the Apple/Nike sports loop are ok, but the strap can get caught and opened up occasionally. So overall I prefer the Apple Solo Loops. I have a few for every day where, and I go 1 size down for the solo loops I use for active sports.
