We had the following 3 different cases with non-Cisco GBICs.

GBICs working fine in 6500s, but not working in 7200s.
GBICs working fine on 7200s, although they appear as unknown type under GE.
GBICs not working at all.

In other words: if you find a GBIC that works, stick with it ;)

PS: The ones made by Finisar had the best results for us...
