I'm inclined to agree, just because of how much more is actually going on pre-Empire. You've got the Jedi Order at its peak, the Separatists, the clone army, the Sith behind the scenes, and the politics coinciding with it too.
However, I personally am more fond of the "original" era because I think it has the superior aesthetic, or at least the aesthetic I prefer between the two. The Clone War era is very clean, sleek, and built-up, very futuristic, but the "original" era is much more leaning towards a dirty, old, scrappy kind of style.
If I had to use an analogy, Clone Wars is like the Millennium Falcon when it was brand new. The original era is more like the Falcon in the new trilogy, and I really like futuristic things that are old and dirty, and they've got pipes and bolts and bulk.
