Rodinal has its fans because it gives superb results with the right films, it's particulary good at bringing out the best all round qualities of modern T grain (and similar) films like Tmax 100, Delta 100, APX100 etc. I used it as my main dveloper for about 20 years before switching to Pyrocat HD.

Rodinal needs careful temperature control accross the whole process cycle including washing to get the best results but then this is true of all developer/film combinations.
