Tamron? Sigma?

[mdwine]

Question:
Sigma 70-200 2.8 vs Tamron

I've researched online for a few days. (and this forum as well) General consensus is that the Tamron is a bit sharper, but the Sigma is more durable and has a bit less vignetting, and seems to focus a tad faster. This seems to be the "average opinion", as there are videos and opinion articles all over the place.

My purpose is "semi-professional", meaning I am getting my photog biz started much of which is portrait oriented and senior high.

I need a better 200 than the kit lens, but definitely do not have the cost of a new or used Nikon/Nikkor.

My question is if anyone has any direct experience with either or both of these lenses, and your opinion on each/both. I don't think that they are terribly far apart in capabilities, and I'm inclined to go for sharper (Tamron), but would like some first hand information if possible.

Your comments would be greatly appreciated.

@MDWINE:

If I've read the OP correctly, you've done your research
and have decided that a marginal increase in sharpness
is worth an increase in vignetting and a decrease in lens
sturdiness.

Assuming your research is solid, your logic is NOT. IOW,
I could hire you as a researcher, but not as an advisor.
