The IQ is really close between those two lenses. Neither will work decently with a 1.4x TC except on a 1D Mkxx body. I think you're right to stick with what you've got. Shoot at ISO 800 and stop down a couple of stops and you can't tell them apart. Save for a 500mm if you want to keep shooting wildlife and birds.
