I've got a 1st gen E3, an Edelux and a Cyo, so the comparison is from my having used them all on the same bike.
I don't know about the E3 Pro asymm. as I haven't yet upgraded my setup to the new LED and lens/reflector yet.
I've got the E3 Pro asym myself. Thanks for the detailed info here, I may just grab the Cyo then. If I like it, I should be able to sell off the E3 Pro and at least break even. Plus then I won't have an unused bundle of taillight wires hanging from my headlight
