They were better attractions because they were good attractions. Each used unique and incredible ride systems. Kongfrontation and Jaws greatly expanded on the tram section and did new, clever things. Earthquake had a clever, fun, and informative multistage preshow even if the ride itself was basically the same.
Kong and F&F are just not good rides. New Kong has some alright moments but nothing in it flows story, tone, anything wise because it isn't a new experience inspired by the tram tour, it is the tram tour sequence lazily slapped onto a different experience. The monsters, the temple, the skulss, the tribes, the horror, the scientists, all the stuff introduced and focused on for the queue and first half of the ride are ignored completely when you get to the "big event" with the 360 segment from the tram tour nad it is all dinosaurs and jungles and spiders and action. It doesn't even look like the same visual quality. Then you end seeing an animatronic Kong head made to scale for the original kong ride not the Kong we just saw in the 360 film. It's a mess. and screens aren't what makes it a mess.
That being said, some nifty animatronics and practical sets would be better at distracting from the mess of the attraction than screens are.
