What's the difference between the Winmau Blade 6, Blade 6 Triple Core, and Blade X?

Across r/Darts threads we read, multiple long-time players argue the Blade 6, Blade 6 Triple Core and Blade X are fundamentally the same playing surface with different backing layers and cosmetic ring updates; one r/Darts thread explicitly calls the carbon resin in the Triple Core 'nothing more than a gimmick.' The Triple Core and Blade X tend to look more premium and carry the latest PDC branding, but reviewers disagree on whether the playing difference justifies the price gap.
