Well, I prefer having flight control options.
I also didn't find computer radios at all hard to set up. If anything it's easier than the "go back and try the adjustment again" manual aproach. I also like being able to go model-to-model without messing with trim settings all over again. I know you can do this with manual radios as well, but they have fewer model options most of the time. My US60 has three flight profiles stored in memory just for that one aircraft. One is a 'trainer' configuration with some of the throw dialed out, one is a dual-y-harness version for full-flying aileron and the third is my crow-mixable variant (that was tough to program).

I would also offer that if you're not willing to learn your way around a computer radio you SHOULD stay with analogs. You could get hurt real quick elsewise (nothing like dialing a null mix or null dual rates).

Finally, I wanted a radio that would display some of what was going on. Believe it or not the simple little graphic helped me understand WHY the radio was doing as it was doing.

Note that it's sometimes easier to fly heli-aero-sail on one radio with computer setup. Helis from what I see (esp competition ones) are much better off on computer radios.
