Im going to say neither...and this is why:
You are chosing between an A&K (great producer) and an SR-25 (By a good producer, but still not high end). Why not get the best of both worlds and get yourself an A&K SR-25. I've had mine for over a year now and I have had 0 problems. Great FPS and performance. Reliable, well built, sturdy. You really can't go wrong with it.
