I'd prefer to stick to the PHB myself.
My gaming group has been running 5e almost since it came out and we passed on Tasha's for making some stuff ridiculously overpowered.
I've been playing D&D for over 40+ years now, and have played all editions - AD&D 1E being my favorite.
Rangers didn't have animal companions.
In either tabletop or video games it always seems like there is just too much focus on the animal companion, and in some cases they have been more interesting and/or effective in combat than their counterparts!
I think too many ppl have read Emo Drow Ranger stories and want a panther, failing to make the distinction that that is a Figurine of Wonderous Power.
Yeah, that cat is more exceptional, that's not what you get for being a Ranger...
