I have a lot of Gregg Homme thongs because they are quite easy to get in Montreal. Gregg is based in Montreal, and I live in Montreal. However, my Gregg Homme thongs are quite skimpy for daily wear, so they're not in my regular rotation.
JM is also based in Montreal, but I only have two thongs from JM. They're comfy, but they don't have that 'wow factor'.
I think CK thongs are good for daily wear. It's a shame that they no longer carry thongs.
