You can just look at the helical parameters to see any detailed
differences. The "Arnott" values are by far the most commonly used, and
would correspond to what most people would think of as "canonical"
B-DNA.
As Tom points out, if you run a simulation, you will quickly move to
what the force field wants, which will be sequence dependent, but really
quite good for B DNA: differences from the canonical form are generally
pretty good (although actual evidence for this statement is sparse.)
