As others have said....
The answer to your question is *VERY* equipment-specific. Given that equipment changes all of the time on all airlines, I would suggest going with the more convenient routing. VS is decent and LHR is pretty efficient for VS-VS connections. The VS Clubhouse is great and you will enjoy much better food and service than a Skyclub or AF Lounge.
Having said everything above, I am not a huge fan of the VS J seats (being 2.0m/6'6" tall and a relatively slim 85kg/187lb) on any aircraft.
