If you're anything like me, you'll find advantages and disadvantages to any developer. I have been using Pyrocat for about 5 years now, mainly because I can actually see an increased acutance in my images vs D76. That being said, I also use Xtol to accomplish a different look. Ultimately, it's best to do some side by side comparisons and see the strengths/weaknesses of each. For how much the chemistry costs, it's a no brainer when it comes to overall expense vs what can gained.
