Best Guitar Chorus Effect ?

I have been looking for a chorus pedal for a while and i found this 3 that in my opinion sounds really good :Electro Harmonix Clone Theory, Boss Chorus Ensemble CE-5 and Electro Harmonix Small Clone Chorus Pedal. I just want one, so I need to know which one is going to last more and have a better sound to play (GNR, Nirvana, Foo fighters, Arctic Monkeys, The Killers...)songs . I need some customer experience.
