im going with the CE-5 b/c i own one and i just love the sounds i get from it. never owned an oc-2 (maybe one day), not a fan of the MXR phasers, my poor Dunlop 105Q sucks too much tone, my QTRON is replaced by the QBALLS. my vote is in!
I didn't see carrots on the list and I can never decide between apples and oranges (specifically Fujis vs. Honey Bells) so I went ahead and voted for the Q-tron.
