For that reason I can comment only from a user point of view.
One of the reasons we are looking at OPM is because we are looking to
for an open source black-oil simulator which we can start testing,
using, and eventually help with the development of the missing components.
At the moment the main priorities we look for are:
- parallel
- unstructured grid.
Higher order discretization methods are less important. CV first order,
eventually second, would be more than enough (at least for us).
From what I understood both grid interfaces can deal with unstructured
grids, but A) is not parallel.
However A) is more developed for black oil applications.

Could you elaborate on what your ideal (conceptional) need/desire is
for "parallel". As a computer scientist, I'm curious as to the
hardware/software issues you seek to solve (make more efficient and
faster) by increased parallelism and all suggestions to achieve a more
robust simulation.
What exactly is your context (details) of what you need/want in an
unstructured grid ?
Grids --> meshes [1] http://en.wikipedia.org/wiki/Types_of_mesh
<link_snip>: "An unstructured grid is identified by irregular
connectivity. It cannot easily be expressed as a two-dimensional or
three-dimensional arrays in computer memory. " If you are not extremely
careful, your simulation will run VERY SLOWLY with an unstructured grid.
