yes, almost the same except they use their own separate firmware updates.
Otherwise the same, yes.
The Z8 with the MOL2 has been available and tested for 4 or 5 months now I think. which has given them time to have worked most of the bugs out now, any that mattered anyway.
Not only is the MOL2 an improvement but the User Interface and the box setup is been revamped from previous models too.
