I'm personally not a huge fan of the Saiyan arc but this is classic Dragon Ball Z. There really isn't much better manga than this. Much earlier in Toriyama's art style, his characters are much more rounded off, and smoother than they would later develop into. They don't have that iconic look that most are familiar with here but it's still the top of the list here. One hang-up I have is Piccolo's dialogue. It's very Olde English. Very proper and I wasn't expecting that. Might just be a translation choice but it threw me off.
