One of each!
Decide this way.
Do you like to fly fast? Warbird.
Do you like scale flight? Warbird.
Do you like to fly up close? 3-D.
Do you like big, expansive maneuvers? Warbird.
Do you want to learn complicated aerobatics? 3-D.
And, just because a plane
can fly 3-D doesn't mean it
must fly high-alpha maneuvers. Just watch out as most are overpowered and with large control surfaces and high speed flight you can tear the model apart. You have to manage the throttle, not just "on and off".
One aspect of the 3-D capable models not often exploited is the wonderful fun you can have playing with the STOL capabilities. I'm more of an IMAC style of flyer than the nose-up hovering type, but a model that can be set for huge flaps, split ailerons, CROW/Butterfly and has control surfaces out the giggie can make for some fun short-field amusement.
But a low pass and snarling pull-out of a Spitfire is unequalled. That and the Mosquito are the only two good looking things the British ever designed; plane, train or automobile.
