I notice no-one has answered the actual question so....

If you are going to have a 3-channel setup then planes made for rudder/elevator/throttle are generally much easier to fly than those designed with aileron/elevator/throttle. To make rudder work it is necessary to have some dihedral built in and this improves overall stability. Most 3-channel A/E/T planes are small aerobats or warbirds and are not at all easy to fly.
