I am using this lens on a Canon, besides the kit 18-135mm f/3.5-5.6 that I have bought with my previous camera. "A little more wide" is nice, but not substantial. The lens also seems to be a little sharper, but, again, not really substantially.
As expected, being faster is the main advantage of this tool, especially in low light, indoors etc. I find it a nice all-around relatively cheap lens, using it more than the Canon's kit one. The decision could be tricky, but I think that the price is quite compelling, unless you choose something considerably better and more expensive.
I must add that I am not a photographer and my opinion is completely arbitrary. Be well!
