Which ND & CPL Filters for Landscapes do you use?

Hey all! I’m looking for a serious ND/CPL filter kit system for my R5 Mark II and 77mm threaded lenses. I’ve done some research and narrowed it down to:

-Nisi JetMag Pro Magnetic ND 82mm kit
-Kase Revolution 77mm Magnetic kit
-Breakthrough Photography Magnetic Dark CPL (3,6,10 stop). (most expensive option)

Does anyone have any experience with these kits or have any further recommendations? My priority is least amount of color cast, stacking (CPL with ND), and travel portability.

Thanks!
