Personally I much prefer the Bakerloo. The seats are much more comfortable than anything more recent. The Bakerloo is pretty low down the list of an upgrade, apparently. Counter-intuitively this is because the trains need substantial refurbishment within the next few years - unfortunately this will be necessary before new stock will become available, so it makes sense to refurbish and then run for longer.
