The original series. The episodes from it are far more entertaining. They contain more humor and center more on Team Rocket (who are the main reason I watch Pokemon). The gym battles are also more fun to watch. Furthermore, I like the animation style better.
I do not mind Johto, though I do find its gym battles dull and some of its filler episodes irritating.
I never cared for AG. May is a better character than Misty, since she actually grows and matures over time instead of becoming as dull as dish water (which is the case with Misty. Even pre-Togepi, I never cared much for her character, anyway. In my opinion, Jessie has always pulled off the ****** red-head archetype better). I do not mind Max, either, since he is a wise-*** kid with a sharp tongue. However, I have never been a fan of contests. I find them boring to watch. The gym battles from AG are also just as stale as the ones from Johto, since they, too, lack the creativity that the ones from the original series have. Furthermore, I HATE most of the filler episodes. The only thing I like about AG is Chimecho, since it functions similarly to an Opium Poppy and even resembles one physically. Sadly, Chimey had to be replaced by a ******* clown, which is not only useless, but annoying.
I have not seen much of DP, but based on what I have seen, it seems just as poor as AG.
