What up, dog?
Do you have an actual source for this or is it merely an assumption on your part? The budget for Tiny Toons Looniversity is noticeably not as big as that of Tiny Toon Adventures, but it's not being made on the cheap either.difference is they wanted it this way because they had a very low budget, not for artistic reasons
The thing is, TTA often needed to outsource its animation to outside studios such as Kennedy Cartoons, Akom, Wang and Startoons due to time and workload constraints (the animators had to churn out 5 episodes a wekk for 13 weeks). TTL doesn't have that problem because it's made for streaming and its initial scheduled episode count isn't as high.
Again, you're allowed to prefer whichever series that you prefer, but don't make baseless claims in order to support your personal opinion.
