Nah, I prefer Z. That was what got me into the series. Dragon Ball is a magnificent series that has everything from good pacing, humor, and fighting, but I just like Z more. Dragon Ball outdoes it in a few areas like more unique fighting abilities and stuff, though.
Not anymore. I was a huge GT fanboy way back, but I eventually found it less and less interesting. Super isn't some incredible series, either, but Beers, Whis, Super Saiyan God, and a few other characters gives the series an edge over GT, imo.
Never read it before.
