The answer to this question is subjective. However, some people may argue that high-quality anime is better than Anime Star because it often features more complex stories and intriguing characters. Furthermore, there's a greater chance of watching an episode multiple times in order to catch all the nuances and hidden references.
Anime star, on the other hand, typically focuses on comedic moments and popular characters. As a result, it can be less taxing on your attention span and can be easier to navigate for newcomers who are trying out anime for the first time.
Additionally, many Anime Star shows end prematurely which means that you're not likely to see everything that you would have liked if you had opted for high-quality anime instead. Ultimately, it comes down to preference - some people enjoy both types of shows while others feel one format is superior to the other.
