Please help me choose!

[malbecone]

I have a wedding coming up and I have some choices for one of these chardonnays:

Salmon Creek
Coastal Ridge
Stone Cellars(Beringer)
Sycamore Lane(Trinchero)
Forest Ville
Harlow Ridge

And for a Cab:

Alice White
CK Mondavi
Glen Ellen
Summerfield
La Terre
Prosperity

I know these are inexpensive wines, but this is for a large group of people and was wondering if anyone has experience with these wines? I need to pick one from each category. Thanks for your help.
