We have seen a number of issues with high-throughput situations with broadcom
nics where under very heavy IO loads the card becomes unresponsive. However,
we only create this situation in our vmware environments where we run a lot of
iSCSI and NFS and RAC, and I've never seen a problem with the broadcoms in
regular IO environments.
But, just to be safe we typically encourage customers running RAC to pick up
some extra e1000 ports if the servers ship with broadcom onboard.
Thanks,
Matt

both are reliable on the hardware side. i use both and never had an
issue with the hardware.
but i had some trouble with e1000 and redhat el5. the driver shipped
with rhel5 did not work with my e1000. switching to intel's driver
solved the problem.
