If I understand the question correctly - which of Apple's standard Watch Bands are on average the best? My pick is the Milanese Loop. You did include "Other (3rd Party)", so that's really confusing!
Sport Band - Fantastic material (never heard of it until Apple announced it), my goto for a dip in the pool
Classic Buckle - Not my fave because it costs the same as the Milanese Loop and Leather Loop, but nice and soft
Milanese Loop - For the money, this is the most interesting and exquisite - a real bargain despite cheap clones
Leather Loop - Got a fake one of these, really nice design but compared to the Milanese Loop, poor value
Modern Buckle - Interesting design, but not for me
Link Bracelet - bit too heavy and pricey for me
