70-200/2.8 + Teleconverter VS Bigma


I was considering a very long zoom, such as the Bigma, and the thought occurred that I might have similar picture quality with a premium zoom and matched teleconverter such as the Sigma 70-200/2.8. The latter option would be somewhat more desirable since I could have a fast zoom without the teleconverter, and the Bigma would be of a more limited use, and the wide end of the Bigma, while desirable, wouldn't have the same usefulness to me.

What do you guys think? Does anyone have info on what such a lens with MATCHED teleconverter would lose in quality, and compared to the Bigma?

I can't compare to the bigma, as I don't own one, and probably never will, but look at the origonal 70-200 F2.8 and a 2x TC
