The sound quality seems a little better than the B3 to my ears and its nice to have the 7 effects. I don't think its a replacement for the B3. The B3 has more effects, is far easier to use, has a much better software editor and is usb powered.
The 3n is made to be put in front of an amp. Its made for the stage were the B3 seemed more a home in front of the computer IMO.
