There is no "best" teacher. Read as many as you can and compare them to each other, and (mainly) to Scripture. As long as they and Scripture (all of Scripture) agree, then they are probably correct on the point you are comparing.
That is what I have been up to as I doubt anyone has everything write.
My concern is all the translations prove that there are errors here and there. My King James may be very close but it seems some details are not as clear or precise as they should be.
