Doepfer A-140

Flawless ADSR, basic controls but 100% effective, living up to Doepfer's one-knob-per-function philosophy.

I find the three time settings to be super muscial, Low for all the percussive/plucky realms, Mid for almost anything from perc/melody/bass, and the High range for longer CV modulation. The dual output seems obvious but ends up being super useful, just as the inverted output.
Haven't really used much the retrig input though.

The only downside I could think of is that it's HP costly compared to other ADSR modules, but then again for the price and how musical it is I still consider this my fav ADSR from the ones I own.
