What makes you stick with a cPanel hosting provider?

I've been helping with a small web hosting business and spending more time looking at how people actually choose a cPanel provider.

One thing I've noticed is that having cPanel itself isn't really enough. People also care about reliability, how easy it is to manage multiple sites, how quickly issues get resolved, and what happens when a site needs to be migrated or restored.

What has been the biggest factor that made you stay with, or leave, a cPanel hosting provider?
