This is not meant to be elitist, but if you ever try grading a feature with a dedicated tool and a control panel, you'll find the workflow and most importantly speed benefits stunning.
I started out in visual effects and compositing. The first short projects I colourgraded were done in After Effects. It's got all the tools and the render quality is excellent. But it's a real hassle.
On longer projects I'm convinced the time spent on the transfer of the project into DaVinci, Scratch or another tool is more than made up because you work faster in those environments.
So I'm in no way saying that you can't finish a project in Premiere at high quality. I'm saying you'd probably be faster in a grading app with a panel.
