It just keeps on getting better. I used to watch the old OVA and I'm sure there's a statistic somewhere that basically shows that the third arc is the most popular arc ever.
Oof, I could hardly get through the old OVA to be honest. The animation, storyline, and voices were unbearable to me. From the gifs and screencaps I've seen, though, the latest adaptation seems really well done. I agree that the third arc is definitely the most popular arc out there, though I don't think I could personally call that arc my most favorite of all the arcs (my favorite would be somewhere between part 4-7; I can't decide just yet).
You speak truth, gentle...Person.
Those parts literally changed how Araki writes Shounen forever. Great examples of one, too. Though, Two and Three were really well done, too despite it following a "safer" writing style.
