They are all good. I have had all 3 up to 35% and you cannot go wrong with any of them.

Some manufacturers have their planes setup a little better than others and that is really the key. The wing incidence and stab incidence, their relationship to one another are importnat. The tail moment is something else that can vary a little from plane to plane and still fall into an acceptable range and still be called scale. Subtle differences can make all the difference in the world.

The extreme flight Yak 50CC is probably the best of all of them for 3D. It exhibits exceptional stability like a 40% and yet still flies insane 3D like a profile. Its the most fun of everything I have done.

The Extra 260 is the most elegant of all to me. I am on my 2nd 35% Extra 260 and I absolutely love them. To me they are the best of both worlds, 3D and IMAC.

The Edge is also a great 3D plane. Again, they are all good.
