Class B is the better of class B and A. (B requires less emissions than A.)
I quote, without permission :), from _Noise Reduction Techniques in
Electronic Systems, Second Edition_ by Henry W. Ott:
" Class A: A computing device that is marketed for use in a commercial,
industrial, or business environment.
Class B: A computing device that is marketed for use in a residential
environment, notwithstanding its use in a commercial,
industrial, or business environment. "
In short, Class a is not for home use, due to the high amount of emmissions
that are allowed. Class B requires lower emissions, for home use, but that
doesn't mean that a class B machine can't be used in a business...
