There is a night and day difference between pre-Tasha and post-Tasha Ranger. Aside from being substantially more powerful, the extra spells with Primal Awareness and extra abilities through Deft Explorer and nature's viel completely change the feel from an undpowered martial to an arguably overpowered rogish caster.
At 13th level you have: expertise in 1 skill, 2 languages, +5' movement, swim speed, climb speed, 4 free spell castings a day, turn yourself invisible as a bonus action 5 times a day, give yourself 1d8+W thps 5 times a day, ignore difficult terrain, favored foe 5 times a day ..... this is in addition to subclass abilities that are pretty awesome and extra attack and spell casting from the original Ranger chassis.
The new Ranger plays more like a GISH/utility guy as opposed to a martial and in terms of all 3 pillars I would argue it is actually one of the strongest classes now. Second probably to Wizard but competitive with all others.
