Find it to be faster than firefox, IE etc, significantly faster in the case of Firefox (opera is not even an option).
I also like the sync function although I couldn't tell you if that was a unique feature (probably not). As an example, if I've left my desktop on with a few tabs open, I can log into chrome from my laptop or someone's tablet etc. and find those tabs instantly under the "other devices" button; it's pretty much seamless.
Chrome also seems much smoother when you have umpteen tabs open although it will crash occasionally and another negative, although it's a rare occurence, is that you will occasionally run into something web based that Chrome won't run, so you have to open IE and launch it there.
