I do like my Arkel GT-54s. I like the organization you get and the ability to use it more like luggage rather than a drop box or something like that. They mount and hold well and a made of a rugged material that will hold up to the rigors of touring. I have talked with folks who have had the same Arkels for 15+ years and the worst that has happened is sun damage.

The tent tube on the right pannier has been quite useful for me as have the other pockets, it keeps me better organized and allows me to access what I need when I need it a lot quicker and easier. Plus I can pack it like I would pack a suitcase.

I think both companies make great bags from what I have seen but I went with Arkels because they seemed to be better for what I wanted and I am glad I did. My guess is the debate between the two is like Vanilla and Chocolate cake, both are good, both have strong and weak points, some like one and some like the other but in the end they are both freakin' cake and who doesn't like cake?
