Its not the steering angle but # of positions it is capable of, response speed, smoothness. I don't think any youtube comparison videos touched up on that one. 2.4s have much faster response than AM Zs, let alone xmods.
If I didn't mention this earlier, 2.4 Zs have the option of PC link(for a hefty 80$) which lets you smooth out every throttle and steering setting you can imagine and they will stay with the car rather than the controller(which I think you can link and tweak the same way).
Just want to throw absolutely everything at you to help you think man.
