I personally find the LX C seats to be hard and slightly narrow. As strictly hard products go, I actually prefer both the PMCO and PMUA seats as well as their respective IFE systems.
Hard product, the benefit of LX is the spaciousness. If redeeming on LX, I'd try much harder to get F seats. Not sure how available they are.

If you don't mind redeeming C, US is an excellent option. And book to TLV!
