I'm posting here since this question is so general, it seemed like a reasonable place. Mod, please move if there is a better spot.

So, I've earned my status on UA for next year and have one more trip to schedule ORD-LHR.

I figure this is a good time to try out some other airline, and British, American and Virgin all have identical business class fares for the days I need. UA is about twice as much so I've ruled them out.

American has the slight edge, since I can earn miles there. I've always wanted to try Virgin, but recent postings I've read makes it sound like much of what we hear is actually hype. Haven't flown BA in years.

Thoughts? Which has the superior business class service on this route?
