Brian, well stated from my point of view. Rodinal is Cheap!! and so am I..also, I like the fact it does last and in a pinch, can use it as a paper developer. Pyrocat, just started testing with it so can't say. For me it is like, stand, semi-stand, develope by inspection, etc..not a silver bullet, but tools to be used.
I like the results I get from Rodinal better than ID-11. Someone else may get better reults from W2D2, guess it is no different than Canon vs Nikon, LF vs ULF, it's about you and what works for you.
Just My Thoughts...
