DD-X was my first developer when I got back into developing film at home. I liked the convenience, I generally prefer Ilford for everything for silly reasons, and the results did not disappoint (at first).
But I do not think I'll be ordering it anymore. Wanted to run my thoughts by you to see if I'm missing anything, or if my experience was atypical:

But I do not think I'll be ordering it anymore. Wanted to run my thoughts by you to see if I'm missing anything, or if my experience was atypical:
- It is on a grainy side. ID-11 and Xtol, both diluted 1:1 and especially full-strength deliver noticeably nicer grain. It just seems uglier with DD-X, especially with Delta films which I found strange, since so many people online say that "DD-X was optimized for Delta".
- HP5+ has a tendency to look flat, but especially so in DD-X. All midtones get compressed into the same narrow spectrum. People's faces look flat and grey with this combination. I tried different times, agitation and even tried diluting DD-X, but why bother if HP5 looks so much better in ID-11 with zero effort?
- Supposedly DD-X gives you effective speed increase, but I never noticed it compared to ID-11 and Xtol. Perhaps this is more important for pushing, but I do not push.
- It is more expensive. This wasn't a factor for 135 but I am shooting mostly medium format, and Ilford insists on 1:4 ratio, this means $2 per roll just for the developer, that's 4x of Xtol.
