To further illustrate I made two quick demos.
The first example is using scenes, with the exact same animations as the second. The scene feature makes this makes it very easy to loop and reconfigure content in any number of ways, and scale to lots of scenes. However, you can see how the animation feels super flat due to no easing on the scene transition, and the timeline not playing until that transition is complete.
The second example is the same animations again, only as symbols on a timeline. This is obviously way smoother since they move with easing and can play their timelines as they're transitioning. The downside is this approach is not nearly as organized and is difficult to scale beyond a handful of symbols. Making these fill the viewport, loop, and move in and out with any level of complexity would be considerably more cumbersome, and require managing your entire project on a single scene with a lot of complexity in your timelines.
