I love the one at LGW which I hear isn't even half as good as the LHR version.

I do like Virgin UC seat layout and seat - recline is poor compared to say BA club world but Virgin is very much the winner in the BA vs VS business class in my eye (got off a 9hour Club World flight yesterday - very mediocre from seat, layout and even service. The only thing I will give BA is the CW bed is more comfortable than the VS UC version but....

...My understanding is VS have the new US dream suite on the LHR/BOM route which I am yet to try.

Have to admit - the suggestion of Jet has thrown me - know very little about them.
