Exactly. DM really has no real additional benefits, other than the DM Choice Benefits.
DM, PM, and even GM are all SkyTeam Gold Elite Plus : what really matters and makes a difference, and PM gets the award redeposit fee waiver, the other important thing.
Any other benefits are all marketing fluff in my eyes and have no real impact. But, of course that is just me. It may be different for others with different travel and redemption patterns.
