Sorry Don, this kind of comments is a typical case of spreading technically false comments - or, to be kinder, close to it...
Unless you do a strictly controlled test your comment has the same technical value as to say - I like this lens more than the other, it pleases me more...
The grater angle of coverage, rightly mentioned in another post, has an influence on the contrast of the final picture, unless you use a good lens shade, something an amateur doesn't give a damn about... An impression of sharpness is linked to the contrast in a picture. Thus your impression can simply be a result of insufficient lens shading, rather than real sharpness.
Saying a lens is sharper than the other without a strictly controlled lens test has the same value as to say - I like this lens more than the other - I like the picture it took better than that of the other lens...
Sure you can like it more (have an "impression", as you say) but it means as much as liking milk more than yogurt... Cheers!
