I agree about the Alpine being very comfortable. I had bought the S8 with sport loop before returning it for the Ultra and the Alpine is way more comfortable than the sport loop.Interesting experiences, especially regarding the Apple titanium lugs.
Of the two bands I have (alpine loop and ocean loop) the alpine is definitely way more comfortable but the ocean one is visually more aesthetic by a lot.
I do like the way the ocean band looks but my main reason for wanting it is for ocean use LOL. I'm not sure how it would look on my wrist since they are on the smaller side. In this case it will be function over fashion.
