The ARR ones had some very nice sights to view. They were thoughtful and made sure the scape was actually appropriate to view.
But in HW and beyond they began to get kinda worse and worse, forgetting the actual idea behind them. They'll make your character stand nose-up against a wall and be like "yep this is it" and you're wondering what the heck you were looking at, when all along it was the structure in full viewed from above; you'd be unable to see such since no perch exists to showcase it. With no weather restrictions many of them were covered up by sandstorms or rain and I couldn't see whatever it was supposed to be talking about and the game was like "yep you did it horray"

So "worth it" can differ from player to player. As an actual experience, it dropped off a cliff.
For some easy achievements it's never been dumber to get.
