I find that class A amplifiers play bass better as well as being smoother in the mids and highs. They can also be more detailed as they make less distortion.
BTW/FWIW there is no such thing as A/AB. That would simply be an AB amplifier. If you see such designations they are marketing terms, not technical terms.
