I think it comes down to a simple question of what you want the bike for. If you want it for the simple purpose of blatting around for fun, and being part of your collection, the Moulton wins hands down. It's probably dynamically superior, definitely more likely to make you smile just by looking at it, and the BF is by comparison, a frumpy boring cousin.

If, however, you wanted to do something like a tour, then the BF wins. I would not want to be stuck out in some cow-town West of Muscogee, trying to find 369 tubes or Capreo parts! Although, frankly, if that's the plac I might be tempted to go with a Downtube for the sake of even more easy fixability. Sell 'em both, buy a DT, and pimp it through the ceiling!
