A couple of comments.... I have the MultiDrive since many years, but an overdriven sound is rarely needed in our songs. Also have the original VT Bass pedal.
There is a bit of tonal overlap, and interestingly, the sounds that work for my bands and my rig are in that "overlap" areas! However, the VT Bass is a bit finicky to tune in to that zone, but with MultiDrive, I can get a tone that works in a few seconds, very gig friendly.
What I like less with the MultiDrive is that it seems it retains an EQ:ed portion of the clean signal, ie it feels my clean signal is in there, but with a wide and modest boost around 70-120 Hz or so. So the low end will get a bit bloated when you kick in the MultiDrive. Not a big problem on stage, but I am not a fan.
OTOH, the VT bass will affect your low end more, and it is harder to mitigate.
Oh, and the noise floor is always higher in the VT Bass, even for settings that sound similar.
