If you take your groomer skiing seriously, you'll notice the difference when you step up to a hard-soled plug boot in a performance narrow last. A good place to start is the Atomic Redster Club Sport 110 Ski Boots and their 96mm fit (most people will need a bootfitter to get these to work). A legit 110 flex (feels like a 120+ recreational boot) and Atomic race-ready stance with plenty of forward lean and a 3mm integrated lift set you up for success on harder snow. Remember, these are the people who build Marcel Hirscher's boots.
