Agree both are high speed blenders, but having been an owner of both, they do operate differently. BT is pretty much automated--several functions may be keyed into the machine to assist with moving the contents at variable speeds, etc. I prefer the VitaMix as I'm able to adjust manually to suit the job at hand. I guess it's just preference--they are both great machines.
Maybe try one of the variable blending options on the sheet/booklet.
Hope you find a workable solution.
