I've only ever used a Wheel - My Tamiya Madcap came with an Acoms wheel radio when i was 10 so that kind of just meant i ended up using one forever, upgraded to an EX1, then an EX1 mars and would never have changed to sticks.
I can drive ok with sticks, occasionally get caught out with the brakes but not tooooo bad.
I personally don't think it's something people should mess about with, it's like changing cars all the time - you see so many people start going backwards with their racing when they start changing things all the time, make a choice and stick at it - you should be able to "master" either with enough practise
