Plus from what I understand if you buy it from a local hobby shop Savox will warranty the servo through the hobby shop so long as you bought it from that hobby shop and the hobby shop is signed up on the program.
This means that if one should fail all you have to do is take it back to where you bought it and they replace it with a brand new one on the spot so long as they have it in stock. You dont have to wait for the bad one to be sent out repaired and sent back.
Of course this all depends if you lhs is participating. I dont own any but if my 7955's ever fail (going on 2 years now) I would consider going with Savox just for the reason mentioned above.
