Brocade broadcasts financial success. Well, if you call an 89% profit drop 'success'

Cheaper, definitely. If you are pushing some serious transfer rates, like a huge back up, FC is better. If you are just doing low fairly low intensity r/w I/O for a web application or whatever, it probably doesn't make much of a difference as both IP and FC are moving data at the speed of light and the disk is going to bottleneck either of them.... Most people would probably be better off buy cheap iSCSI or other IP switches for most workloads and spending their cash on more expensive SSD storage instead of disk, which will make a performance difference... or just skipping the SAN altogether and buying a hypercoverged system, or letting Google Cloud or AWS figure it out for you.
