My opinion is a Havoc SS due to the build quality, strength, low weight and amount of flight abuse it can take as demonstrated by Pablo. You have the choice of Electron or pneumatic gear. A Kingtech 210 is awesome in it. The T3 is nice but to me Chinese jets still have a way to go to reach the same level. I examined a T3 in detail and was somewhat turned off by how "heavy" parts like wings and stabs felt and a few other things. The T3's I've seen flying are using a 260 or 310 turbine, so any $ you saved in kit cost you need to spend on the turbine. So when ready to fly both are pretty close in cost, but I'd still go the Havoc SS route.
