As a DM <with a Platinum DL Amex>, I don't keep stats, but, I feel as though I get about 95% UGs, and most of them at the 5 day DM UG window. I travel 100% for pleasure, so, I guess I fly opposite of business travelers - particularly since I constantly see DMs posting there that they rarely get UGs. The UGs I usually miss are when I make a last minute same day change.
That said, I really can't remember a single post that leads me to believe that paying extra for an Amex Reserve card makes any noticeable difference.
Also, I can't vouch for UG percentages on other airlines, but, from what I've read here, you should do better on Delta.
