Depends on what you call power.Hot Take (not really):
You could give the Ranger its base class, and add to it all the Tasha features (without removing anything, just in addition) AND add the Beastmaster archetypes to the base class and it still would be less powerful than a paladin or some clerics.
The ranger is better at some roles than paladins and clerics at many aspects and waker at other ones.
That kind of the discussion of the thread. What should be the ranger be strong at.
