Go to DXOMark and compare the different brands to see which is the best then make your choice based on what available within your budget.

I have the canon 70-300 (approx$650 new) I bought from canon refurb (about $365) and love it. Sharp focus and not too heavy. Highly recommend!
It is a well recommended lens, I certainly have no problems with mine, which I acquired used on ebay...
Good luck
I bought the Tamron 70-300 used for about £100

For the same price, the Canon is better.

In a case like that, I always read reviews, as many as I can find. One lens is going to cost more than the other, and you have to ask yourself what you are getting for the extra cost. Sigma isn't your only alternative. Tamron has been coming on strong with new lenses.
I like all the lenses I have, so I would recommend them, but maybe I could have done just as well, or better, for less money. Reviewers go through lots of equipment, so they can see differences that a person with one lens cannot.

Good suggestion. When you select the lenses, you can also select the camera you will be using. That makes a difference in their ratings.
Buy Nikon glass and end all your worries..

Thinking 70-300mm f/4-5.6 IS USM
I have that lens, and it is very good up to 200mm or so but there is a loss in performance as you go to 300mm. I don't know if you have read reviews on the lens, I assume that you have but it reviews quite well. One thing that is odd about that lens is that the front glass turns on focus which makes using a CPL difficult, especially if you are using a lens hood which I recommend.

As hinted in the introduction the lens features an UD (ultra-low dispersion) element which is quite unusual for a consumer grade Canon lens. This special kind of glass is usually only used in Canon L (professional grade) lenses.
In the lab the effect of the new design became pretty obvious with surprisingly high resolution figures throughout the range. In fact the data was so impressive that I was already wondering whether I had mixed up the RAW files with a (supposedly) better lens.
The lens produced very good to excellent MTF figures. As to be expected the performance is best at 70mm with excellent center and border quality at all tested apertures. At 200mm and a little more so at 300mm there's a slight decrease in resolution but the results stay easily within very good territory reaching even excellent center figures at the respective performance peaks. Compared to true L grade lenses the contrast level seems to be a tad lower at 300mm. Nonetheless this is truly baffling for such an affordable lens.

I bought the Sigma 70-300mm, DG, OS and I love it. I am getting wonderful results on my 70D.

Not a fan of Sigma. Stick to Canon or try Tamron. My $.02.
