My experience exactly. I've owned both the 80 and the 100, and finally got rid of the 100 for FOV considerations. The difference in sharpness is definitely visible in real life shooting, but the 80 resolving slightly less detail was never an issue to me.

One caveat: the 100 has less distortion than the 80, but again, this is a minor issue (to me).
The 80 is a very well corrected lens. My advice would be to only get the 100 if you prefer the FOV or care about the (lack of) distortion.
