I shoot it fairly often. Like it best at 1600, but sometimes shoot it at 3200 when I need the speed. Kodak Tmax Developer has always been the best for me for both Delta 3200 and Kodak's Tmax 3200 films. Ilford DDX is said to be similar in image quality to Tmax Developer, so if you live somewhere where Ilford developers are easier to get, it should work fine, too.
