I used a neck strap 20 years ago. Left the hobby and came back, along with a neck strap. Just a lot easier to not have to worry about where your hand is, how to hit the switches its. I got a tray for my wife and she let other people try it - they loved it till they found it actually cost money.
I use a rubber ducky antenna on my TX so that I don't have that "hit the prop" problem at all. Only problem is that on the one TX I have with a regular antenna, I've forgotten to pull it out - once. 
One thing though. I carry the TX to the flightline and don't clip it to the strap before I'm totally ready to fly. Its clumsy to have to unclip, set it down, fiddle with the needle valve, pick it back up and clip it on again. I just hold the tail between my legs and do all the prelim stuff, then clip it on.
Not only did I clip the antenna with my prop, but the throttle stick brushed up against my shirt and revved the engine up, which startled me. I realize that I'm going to have to pay more attention with the neck strap. Did you also notice how you can't really see the entire LCD screen, because the strap is in the way? Another inconvenience for the convenience of a strap!
