Well, yes, but criticism of Kanto usually revolves around the non-existent story, humdrum towns and general ubiquity. I genuinely cannot remember the last time anyone expressed the view that the original 151 was the worst instalment of species.
Hahahahaha this response is so funny to me
Not sure how I feel about just ranking them and leaving, because I think people add assumptions to threads like these (see above), so I'll leave my opinions on why I am ranking them this way.
7. Alola
-I feel bad saying this one is the "worst" because there are so few Pokémon and it was an odd setup for a region/game, but I don't have many from Alola that really stand out or that I feel like I need to use in other games. Also, I think I like the regional variants better than the brand new Pokémon, which bothers me a good bit.
6. Johto
-Mostly for a lack of Pokémon and evolutions that enhance certain species. I feel like overall this region had a lot of cutesy Pokémon, which isn't a bad thing, but none of them are my favorites or stand out in any kind of special way.
5. Kalos
-I actually really love Kalos and the games associated with it, so this ranking surprised me, but the only reason it is being beaten by Kanto is because there are fewer Pokémon to take into consideration. And I think some of the designs are a little off, like Pyroar's mane being so smooth and pointy. I enjoy a lot of the things that the Pokémon of Kalos tried to be, and had there been more they would most likely be ranked higher on my list.
4. Kanto
-I think there are a solid number of standard Pokémon here. I am not a huge fan of some staples, but I genuinely like a lot of them for their designs and evolution lines. There is a good balance of simple concepts with good designs.
3. Sinnoh
-One of my favorite things about these Pokémon are the number of evolutions that older Pokémon got because they completed so many of the evolution lines. It's so weird to me to think that a Pokémon like Roselia was a standalone until Sinnoh and is now a full line. I wish they would return to this at some point. But I also think that there are some other great Pokémon here, and I overall enjoy the silliness of most of them (Floatzel and Gastrodon being two that come to mind right away).
2. Unova
-I can't tell you how many Pokémon from this region that I absolutely
love. It brought back the same idea I just presented with Kanto, a good balance of concept and design, but I think they enhanced it this time around with Pokémon like Ferrothorn, Shelmet/Karrablast, and Garbodor. I think Unova had the best cohesion between region and Pokémon, so I really appreciate that.
1. Hoenn
-Need I say more? I honestly love every single Hoenn Pokémon. It's probably some deep nostalgia or something, but I don't base a lot of my opinions on "oh, it's the original thing!" but I think I've spent so much time in Hoenn that it's hard for me to dislike many things. There are definitely imperfections or parts I wish changed, but in terms of Pokémon I just love so many that it would be rude of me to rank it any lower.
