Well, I have customers running both AIX and RHEL, and my experience this far is that AIX still outperforms RHEL on I/O performance. It might be that the systems running AIX usually have more expensive/higher performance equipment connected to them than their RHEL counterpart.
I also prefer the device management on AIX compared to Linux (IBMTape, storage device management, LVM) aswell as the cluster capabilities that are provided. But in the end, I guess it all comes down to what competence you have in-house, and what the budget is. Linux is still a very competitive option.

I'm looking around for an update on my expectations that power hardware and AIX is more performant per memory/CPU/IO than x86 and RHEL. I know this topic comes up from time to time; I don't think I've seen it rehashed particularly recently. I'm an advocate of AIX for this, but I wanted to check signals and experiences, again. - Allen S. Rout
