It's what's shipping with CentOS/RHEL 7 and probably what the vast
majority of people are using aside from perhaps the Ubuntu LTS people.
Does anyone really still compile their own latest kernels? Back in the
mid-90's I'd compile a new kernel at the drop of a hat. But now it has
gotten so complicated with so many options and drivers etc. that it's
actually pretty hard to get it right.
