1) Toriyama didn't do all of DBZ, like the FFC release of CT, underlings took over after the first story and Akira also did the last of the series. If you want to compare, Toriyama did more of Dragonball than DBZ. Also, DB>DBZ.
2) How the heck can you say that the CC characters are more realistic!?! Hello? Kid! Almost none of the female dimensions are realistic (except maybe, like Macha & Sprigg or something...). I think we have to take in account that all of these characters take place in an anime/manga world...So nothing's 'real' and everything's up for grabs.
3) I loved the look of all the CT characters. I mean, the little touches like having Magus w/a widow's peak were things that really made the characters stand out. I mean, the complexities of Robos design in and of itself were amazing. He looks futuristic, and yet, still from a very different world's future. Frog too was nice. CC had some good designs, but I just didn't think many of them stood out a lot...A lot of their costumes seemed just like that...costumes. Not many of them seemed like they were actually wearing the clothes of the trail-worn traveler and hero. But of course, many of them weren't that...so maybe that's why I didn't like their designs...they don't fit right...
