Some people find the ABA one good. It's the same basic design. The differences are in materials, as you said - which can make a difference to the fit and comfort, as well as support offered by the MT, also the width and padding of the straps - the ABA ones are very thin - and the waist band - some are quite thick, padded, etc, and that all makes a difference to the way it works for you.
If you can, I'd go and try a few on to see which suits you best.
