In regards to the AF, it has come up short a couple of times, but you can always go manual if you prefer. Having said that, it is very sharp across all focal lengths and allows me to theretake some good low light shots. In fact, it is heavier, by far, than my 70-200. I also have the same set up (60D with the Sigma) It is a heavy lens. Other than those specific conditions the AF of the old 30mm was pretty decent.but the 18-35 seems to be much better in that regard and the AF is almost, but not quite, as consistent as my Canon 15-85. In most real world situations it's AF was fine, but it has problems with small targets, especially if they are low contrast and it was even worse with small low contrast targets in low light. My first copy was decentered and returned, my second copy back focused and I drove out to Sigma on LI to get it adjusted. Too many of them also had front/back focus issues. I'm taking about the older 30mm prime, not the current one which like the 18-35 has much more consistent AF. I find it very strange, how Sigma seem to have more AF issues with their primes, than zooms. Looking for light in all the right places.

While there are occasional auto focus misses with the 18-35, I found the AF on this lens to be much more accurate and consistent then on my Sigma 30mm f/1.4 EX DC HSM. I also have an older SIgma 30mm f/1.4 and and had to take it to Sigma to address a front focusing issue I was having with it. On a 600D you will primarily be supporting the body on the lens not the lens on the body. I have my 18-35 mounted on my 60D and I can tell you it a very big and heavy lens. I assume you meant 600D, not 60D since you list the 600D as your camera. My sigma 30mm 1.4 (old) one has front focusing issue. Not sure if Rebels can keep up with 18-35 focus requirements. Did you notice any focus issues with 18-35 and 60D.
