FC is better
"What small or medium company is going to set up a greenfield Fibre Channel SAN these days, when iSCSI is rampaging around?"
Given that it is cheaper and easier to buy a pair of Qlogic SANbox switches and set up zoning, than to buy a pair of decent wire-speed Ethernet switches and dick around with STP/QoS/trunking/VLANs/etc. to obtain equivalent performance, I'd say that any company that can crunch numbers without developing haemorrhoids would see the benefits of going the FC way.
