I need help with picking one out of two PCI cards

I decided to install a PCI Card into my system. After a while, I managed to find two older cards, which i salvaged from some thrown-away computers. Please help me pick one...

The first card is an MSI PC60G. The second card is supposed to be Z-Com XI-626.

MSI PC60G because it has wireless G. The Z-Com appears to only have wireless B, which is slower than molasses running uphill in the middle of winter.
