With things like Software Collections and IUS you get to run the latest stuff on a rock-solid base. I don't want to upgrade my kernel to get a newer Python or NodeJS release!
Software Collections are honking great, I'm actually looking at moving one of my Python 3 apps from Fedora to CentOS purely because it requires a version of Firefox that supports the Java plugin (selenium script that has to use a page with a java applet...) - since RHEL/CentOS stick with ESR releases I'll at least have 18 months to hope the applet goes away.
