Is the Sigma 17-50mm DC EX HSM OS f2.8 a good upgrade?

Just a quick review and comparison between my new Sigma 17-50mm OS lens and my Canon 18-55mm, 24mm, and 50mm STM lenses. Is the Sigma a good replacement for all 3 Canon lenses? The answer is....it depends on your needs. Watch and hear my opinion with image samples.
