I have both styles of the new loops as well as last year’s leather loops. For general use, comfort and durability day to day, the new bands win. The leather is nice looking and fairly comfortable. However, it doesn’t do well with sweat, water, and sporting activities, as it is remi-rigid. The leather if for more of a casual wear during the day or night, when you know you aren’t going to get it wet, scratched, or otherwise damaged.
