Where can I compare homeschool curriculums to choose the best one for my daughter?

In particular, I am looking for a preschool or kindergarten curriculum with religious emphasis. Suggestions or links are appreciated – the ones I've heard the most about so far are Before Five In A Row / Five In A Row and Weaver / Weaver Interlock. Comparison website links would be most helpful!

I had forgotten all about Sonlight, but I've heard great things about it too – thanks!

Do you mean a review site of homeschool curriculum? The only one I've used is this: http://www.homeschoolreviews.com/ I have found it useful and posted a few reviews on it myself!
