what was the best anime era??

You know what? I'm gonna say the unexpected answer and say BW was good... in terms of art style, I still haven't watched much other than clips I saw as a kid.

Also, I really like the more selfish and more childish personality the Kanto group has in the first seasons. And the art style.

Journeys was my favourite though as it was the first time I watched a series when it was new. I liked the characters and the fun feeling of most episodes.

The Kanto and Orange Islands seasons had the best writing. Pretty much every episode has something memorable and funny. Though Ash, Misty, Brock, and Tracey don't have major character arcs like the characters in other seasons, they bounce off of each other really well, making even the filler episodes enjoyable. Also, Team Rocket were easily at their best, as the writers actually developed their backstories.

Johto starts off pretty well but gets really stale after a few episodes. The writing loses the punch it used to have and every episode feels more or less the same. Unfortunately this is a problem with the seasons thereafter, in my opinion.

Of all the later seasons, I like Journeys the best, particularly toward the end. Bringing back all the old characters was an amazing trip down memory lane and made me feel like a kid again. :)

Journeys and Sun + Moon tie for me. Yes, I know they're the two newest ones, but the plot seems to get better and better throughout the series. Journeys has the best ship, and many fans of the series know what it is! And Sun + Moon was the series I watched when I was littler and had less experience with Pokemon, teaching me all about it while bringing me my favorite region.

I love XY, XYZ, and Sun and Moon, but Journeys is good, too.
