I took Rhino's comment to mean that he specifically does not like the twisting endcap for constant on because it takes two hands. To me not a big deal for a defensive light. For a general purpose light I actually like the clicky tailcap. I still usually carry my E2DL at work because I like how the tail cap is protected and it is easier to turn on with one hand.
And you took it correctly, sir!
I do have several SureFires that are twisty, but I still prefer clicky if I have the option.
