Least and favourite Pokémon Region?

My favourite region is probably Johto. Yes it is quite small without Kanto, but I love the aesthetics of the region. It is based on the area where I presently live, so there's that, too.

I love gen 5, but Unova is one of the most boring regions. It's literally a circle.

My least favourite region is Hoenn. I do not like gen 3, and Hoenn itself is a big part of that. I understand that half the region being water closely relates to the themes of the narrative, but that doesn't make it fun to play or explore.

Adding extra HMs such as dive to expand the range of things you can do in water both helps and hurts it. Yes, you can do more to break up the tedium of surfing, but that's another HM taking up a move slot on your team, or possibly requiring a second HM slave.

I did think that Galar might be my most hated region. But despite being painfully linear and the game's poor presentation and graphical issues, I actually like a lot of the towns. The wild area probably is the worst of it, using awful textures and being glitchy, especially with the online connection active.

I would also suggest Kalos for being based on France, but jokes aside, I actually like the region a lot.

Most people hate on Johto but when I played through silver I actually really enjoyed it but my favourite is a tie between Kanto Hoenn or Hisui and least favourite is Unova and i've never played Kalos and Alola because I never got a 3DS and I couldn't find and emulator compatible with my PC or phone

I don't know about my least favorite region but my favorite is definitely Hisui.

since it’s the same region

My favorite is Unova and least favorite is Hoenn. I despise it so bad, and all the Pokemon are forgettable. The game is a mess too.
