I like the whistles one - the strap is long while most of the others' is too short and I always find it a pain with bulky coats.
I also prefer simple and understated of gold faff and tassel, which tends to date a bag to a trend/season.
Only concern is thin straps - if you fill a bag that big with an ipad and a bottled drink, will your shoulder get sore because the straps are too thin for the weight? I always transfer contents of current bag into new bag I'm "trying out" in store as a lot of bags don't sit well on my shoulder with my stuff in it (as opposed to empty).
