Depends on what you're looking for. The TW Pro is certainly the high performance park-specific ski. It's pretty stout, has a lot of pop (carbon ollieband), and an amazingly low swing weight.
The Chronic -- especially the 2019 redesigned Chronic -- is an amazing all-mtn ski as well. Think about what you're looking for in a ski. Do you want to exclusively ski park? Just need it to perform on rails and jumps? TW Pro.
If you're looking for that ever-versatile mid-90s waist-width ski that can ski the whole mountain really well, and crush it in the park, opt for the Chronic. Hope that helps!
