I've never heard of Saner. We've had Anker 1900 mAh batteries in our 2 Evo 3D's since August with no complaints at all. There are some lengthy treads on XDA in the Sensation&Evo 3D forums about Anker&Chichitec batteries. They seem to be the closest to claimed mAh, about 18% more than the OEM battery. I don't think you'll go wrong with either the Anker or Chichitec.
