If you consider DM and EXP to be equivalent value, the implied monetary value of 4 GUCs is $650 (DL requires $265k of card spend for DM, AA requires $200k card spend... Assuming that most of that is non-bonus and that there's about a 100 basis point difference taking miles instead of cash back, that extra $65k is about $650 foregone).
Even with spend DL requires you earn MQM. Requires both personal and business Reserve cards to get enough MQM.
