The diff in benefits between GM and PM is, as was stated above, not much - threshold gifts or PMU's (80% of PMU's go unused per DL, so worthless to most people), and the upgrade priority.

If it were me, depending on travel patterns, I would either get just under 75K with DL or get CO SE. I am purposely avoiding getting to 125K MQM since I absolutely think the benefits for DM are minimal vs. PM.
