ghosh that seems like the most annoying travel blogger ever to me… I would not enjoy flying with him saying stuff like this during the flight. Anyway there is a bit more clear review and comparison at Live and let’s fly if you search for compare Swiss Lufthansa first (I just joined and can’t post links yet)

For me the ground experience at LX is subpar compared to LH with FCT etc. seats are more modern at LX and private but the cabin more packed. Food wise it’s salmon vs. Caviar. Same same but different. If you can do one either way and then enjoy comparing but when in doubt I’d go with LH and try to connect allowing some time in FCT.
