I usually take a 25,000 RDM benefit and it does not count as MQDs.
As has been pointed out, the GUC's are worth much more than $1000. If you don't fly internationally, take the 25,000 miles 3 times. those 75,000 miles are worth at least $750 at $.01 PWM and more if you use them judicially.
Other benefits that don't have a specific $ amount value are the DM phone line, better IIROPS treatment, early boarding if you need overhead space, bag tags (just being facetious with that one) and other intangible benefits.
