DB, DBZ or DBGT?

Which out of these three, DB, DBZ and DBGT is your favourite?
Mine would have to be DBZ because Its more interesting than Goku's childhood, and in the future it gets boring and loads of characters arent in the series.

my fav is also DBZ but i also like the ending of DBGT cause for once in an anime it shows u that there will NOT be any more after that!!!! everyone goku knew is dead ecept pam who is really old and he is trained and becomes the worlds strongist which wasin the end his aim so it prooves that there cant be more!!! but the problem with DBZ is it just kept on going which got anoyin after a while and tehre was to much talking
