The Be packages had a major change 1 April. The best summary of the changes
is here. Also have a look at
this document. That tells you a lot about the technical differences, but hasn't been updated yet for the contract changes by MKD who produced it.
As I see it, the only reason now to go to Be would be if your were a really keen gamer so wanted to get Interleaving turned off, to improve your latency/pings.
I think both of them run your line uncapped for a few days of DLM, so you will be able to see what it can actually do. Then they let you change if you want to.
Re your line speed, I assume you have the ring wire sorted, either by an ADSL Nation XTE-2005, or a BT iPlate, or
this way. It can make 2Mbps difference quite often, though usually less.
