I'm not going to speculate on what future schedule changes may happen with TK, but on a straight up comparison of the two hard products, I would choose TK over LX any day. Swiss has a fine F product, but their business class seats feel like a cramped coffin to me when reclined, and I just don't find them particularly comfortable. I don't know how the actual measurements compare, but I feel like I have more space in the TK seat; less privacy, but more space. I'm certainly not ready to start switching my TK flights over to other carriers.
