The "non-Macro" I have is also f2.8. The "macro" version is supposed to be a little better quality, a little shorter minimum focus distance, and a little more costly. I recommend the "macro" version.
There is also the "consumer" lens: Sigma 18-50mm f/3.5-5.6 DC that is very inexpensive and not an "EX" lens and no better than the Canon consumer "kit" lens.
