Chi-Chi's is much easier to pick up on just by listening, because her grammar is weird but her pronunciation is perfect, but I used to have a lot of trouble understanding a word out of Goku's mouth, because his pronunciation is just like - "what? WHAT?" Son Goku, strongest person in the universe, voiced like a girly hick. HOW CAN YOU GO WRONG.
The VIZ manga does make a pretty good effort at showing off the character's accents - Goku uses a lot of weird abbreviations, which is hard to read but then again, accurate, and of course they appear to have a lot of fun with Chi-Chi... actually, I really like reading the manga, just because the translation is accurate and they do a good job with keeping the feel of the Japanese speech patterns intact - as best you can with a neutral language like English. (No feminine speech, really - no real formal language that doesn't also sound stilted, etc.)
