If it was gifted, why not keep both ?. Otherwise, shoot each under identical conditions & decide for yourself which one better fits your needs. One point I will mention though is that the Nikon will hold it's resale value better should you decide to sell one or the other.

About 6 months ago, I bought a Tokina 11-20, f2.8, Pro DZ. Since I have been helping my widowed friend re purpose her husband's equipment, she gifted to me a Nikon 10-24, f3.5-4.5, AF-S DX. The question that I am faced with is, which one do I keep and why. Maybe I should keep both of them? As always, your input is appreciated.
