Did the IOPS (and better yet, enhanced IOPS) help any big user? DataStax and Eleasticsearch Inc recommend to stripe instance stores (doing raid0), which in the cloud is not the worst idea as long as you have multiple nodes and proper ring designed. That being said, now I lose the ability create snapshot because the volumes are not EBS. From my experience the IOPS isn't very stable.

Provisioned IOPS are quite stable, in my experience. That's their entire point.

But with AWS' provisioned tiers you're kind of losing out on your cost savings...
