Bancor is nothing more than a merger of 2 already existing platforms. First is the ability to seamlessly swap one token for another. This is what shapeshift does and it does it very well. Second you will have the ability to create any tokens you want with ease. This is what the waves platform does. Waves platform is also a dex where the created tokens can be traded. Sorry but Bancor sounds like a loser to me
Surely you can't be serious. You are comparing an internal, automatic swapping mechanism in Bancor with a third party web site (Shapeshift) which is simply a front end to another third party web site (the exchange). Bancor is the ultimate in liquidity, sending your coins to one web site and hoping they can connect to another web site to buy or sell on your behalf is not.
