They're both their own synth. The Mopho has more snap and punch in the EGs. And more low end balls. But can't get anywhere near the sound of the Evolver. I have them both, they both have their purposes. But if i had ditch one, or didn't have any and had to choose one to buy, i'd sell the Mopho/buy the Evo. It's more synth for your money.
