Actually, the Swiss Exclusive Magazine is usually just 4-6 pages, whereas the German version is a real magazine. I usually pick it up in German SEN lounges.

Regarding the OP's question, there is no such thing as a "LX SEN" vs. an "LH SEN". Yes, there are different card layouts, and there is a bit of localized comms such as the Exclusive Magazine, but in terms of features, benefits etc. there is no difference at alll. The system is not able to distinguish between "LH SEN" and "LX SEN", all numbers always start with FQTVLHxxxx and are recognized as LH*G.
