17-50mm F2.8 EX DC OS HSM or 18-50mm F2.8 EX DC Macro?

Hi all,

I want to know which of these SIGMA zooms for my SD15 is better. 17-50mm F2.8 EX DC OS HSM or 18-50mm F2.8 EX DC Macro?

I want to know which of the two zoom delivers sharper and gives better final image quality.

Do these two zooms would be obsolete with the SD1?

Thanks.
