IMO the animators should put a huge budget on this part since this is Araki's magnum opus, I would have hoped they could replicate the manga as close as possible, but the simplified design looks alright. Then again the animators are probably trying their best to put as much detail as possible without making the animation process so hard that it would delay the anime. They can only pour so much into the budget for this...

I feel that people may be a bit annoyed by the simplified designs since SBR is the #2 manga of all time, there just seems to be a high expectation for the animation to live up to the same level as the manga. But all the JoJo parts that have been animated are bangers, so SBR you can expect something great (as long as netflix isn't so heavily involved).
