The deciding factor for me on both MET Premium and TWD Premium was the light show. Red inserts all day was a big turnoff. I modified the left ramp on TWD with washers to align the rising flap with the ramp and it shoots great (on location too).

I think the IMDN art package and flow is much better on the Pro.

DP Pro was a location decision, didn't see the value going for a Premium.

Xmen Magneto is another great theme for me as well, the rules are not that hard to learn and it's packed with shots. The art package is great as well...IMHO.
