The Tactical & Desert Tactical use Carbon Steel for Barrel/Action, where as the Ridge Warrior uses Cerakoted Stainless Steel for Barrel/Action. (This is the biggest difference among them.)

The Tactical & Ridge Warrior both use Fluted Barrels, the Desert Tactical has no Flutes.

Other than those differences, these rifles are the same. All are TBR, use the same 20MOA Rail & Accutrigger. All have threaded barrels for Muzzle attachment or Suppressor. All use 24” Heavy Barrels. All use the Accustock. Mostly comes down to which color stock do you prefer?
