I would have to say mac because of how it isn't bound to a unit and doesn't really need to be microed.
I lost this one game because of a successful make.
It was a total vehicle war. I had four cobras unpacked in front of my base, along with some wolvies and scorps. The cutter guy came in and took out my four cobras with MAC and unpacked his within range of my base. His army flooded in and slaughtered.
When life gives me lemons,
I make beef stew.
