I would pick Swift over Clemence. I like smooth and lightweight leather for my bags. I enjoy my swift Kelly flat sellier and gulliver/swift mousepad a lot. I have a travel Birkin and Sac a Depeche in Clemence and both are heavy. I guess I'm more a fan of smooth leathers that are soft or velvety to the touch like swift, barenia, box, chamonix, and evergrain.
