NM-HDA (High Density Analog) only supports FXS and FXO with the extension modules. NM-2V is a module that supports the same FXO, FXS, and BRI. Function wise, there is no difference, but the NM-HDA has the better DSPs and support more channels.

Those are good to have and you could use those in any wic slot but you won't be able to use them in the NM-2V. I think you could in the NM-HD modules though.
