In all honesty, apart from the fact that Dio is the final boss of the part which introduces the most famous aspect of Jojo(Stands), or that Za Warudo is one of Jojo's biggest meme, I don't quite understand why people seem to put Jotaro VS Dio as the biggest rivalry in the series.
The two has minimal interactions and chemistry, Jotaro's reaction after defeating Dio literally was "meh". Even Joseph had more personal grudges with Dio than Jotaro does.
I just don't understand why Jonathan is pushed to the side so much just to promote Jotaro as Dio's "one true nemesis". Like in Eyes of Heaven, for exampe.
