Replying to Ski Boots Recommendation

Hey all. I'm looking for some advice on ski boots. I know a lot about skis, gear etc. but not too much about boots. I've been into big mountain my whole life and recently started skiing park this year (just basic rails, 3's). I've been skiing on Atomic Hawx Ultra 100 and recently got a pair of freeride Dalbello 100. Are ski boots similar to DINs where you want higher settings for more aggressive skiing? And should I look into investing in a pair of park boots? The Dalbellos seem mostly fine in the park, but maybe i'm just unaware of the difference. Would appreciate thoughts.

FYI: I'm currently on BC Camox, and likely getting a pair of Faction CT 3's for sending harder (looking to learn 5's, backflips next year)
