I like to use JR servos. The 8711 is powerful and reliable with excellent quality metal composition in the gear train. They last a long time and just do not fail in my many years of doing this. I have had a couple 8411s fail over the years. Never in a 'hard over' way. Never lost a plane to a JR servo. I have used nearly every brand out there in over 47 years of doing this, and use Hitec, and Savox on some less expensive planes and in expensive ones on secondary functions, but on the main control surfaces, my first choice is JR high end.
