I have the Axiom LaSalles, and I
really like them.
I've done tours with them in various parts of North America, in Europe, and in Australia. In total, I've covered probably somewhere in the neighborhood of 6000 kms with them.
My biggest tour with them was 3 months and 5000 kms in Australia.
If I had to buy a new set of panniers (and I don't have to yet), I'd get a new set of Axiom Lasalles.
