Don't expect too much Team Aqua/Team Magma. They kinda were just there for the most part.
Even though I looked over donavannj's post, I'm still kind of lost on exactly where I should begin as far as the anime goes. Like, I suppose it was worded kinda confusingly in a way (no offense don!), because I'm not sure if I should really start all the way from Hoenn or just go with Sinnoh and then Unova and Kalos and marathon my way through, I guess. :x
Straight through does work.
However, part one of my suggestion was to get caught up on XY first. Part two was to watch Hoenn and Sinnoh in order while staying caught up on XY. Each series can be watched with minimal input from the prior seasons.
Part three of my suggestion was to possibly consider skipping Unova. Unova has moments that are worth watching, but the pre-series hype as well as the early series buildup to something promising kinda fizzled out and left a feeling of disappointment. If you want to judge for yourself by watching it, you can, though. You just might enjoy it more than I and many others did if you have tempered expectations for it, compared for the higher expectations we had for it. If nothing else, watch episodes 82 through 100. My personal favorite part of the series.
Personally, when I was getting caught up, I did something kind of weird where I was watching DP as it was airing, and getting caught up on what I missed of it via Cartoon Network's weekday reruns, while simultaneously picking up Kanto, Johto, and Hoenn as they hit Pokemon.com's PokemonTV site. The method I used was a slow way to go about catching up. I was never really marathoning Pokemon at any point. I was just catching up with maybe an epiosde a day, maybe more if I was more than a day behind on the reruns, or if I knew I wasn't going to have time on any other day to power through the 5 PokemonTV episodes for that week.
If you wanna be lazy and watch the dub, the first 5 regions are running on the USA PokemonTV website (
https://www.pokemon.com/us/pokemon-episodes/), though 3 of the 5 regions are late in their adventures (Ash has 8 badges at the point Unova is at, 6 where Johto is at, and they're in the Orange Islands in the Kanto cycle; Hoenn and Sinnoh are only at about 2 badges in each, if my memory of the contents of the episodes currently up is correct).
