I would go with the Sukhoi. I am building one with a DA 100 and all JR 8411s. This is one of if not the best arfs I have build. The quality is amaizing. I have seen several of them fly and they will do just about anything from imac to wild 3D. Mike McConville even won the Unlimited class in an Imac contest with the sukhoi competing against several 40%ers.
