I prefer the US hard product over even new LH C, although I'm only familiar with the A330 for both products. Can't beat all aisle access (1-2-1 on the US A330 vs 2-2-2 for the LH version). The window seats are great for single travelers. I find that my perceived personal space is noticeably greater than on LH, sort of half way between LH C and LH F.
