The two top trims are the Premier and the High Country. I honestly don't see much difference in them with the exception of the color of leather seating that is only available in the High Country. Personally, I believe the Premier is the equivalent of the LTZ. May I suggest that you go into Chevrolet.com and select the ability to "Build Your Own" and then compare the two trim levels. I've never compared the Premier and the High Country, so I don't know the specific features that distinguish them. Good luck. as a note: We are extremely satisfied with the Traverse Premier (2020) that we purchased. Ride comfort, quality control, fit and finish, performance and economy are all excellent--from our experience.
