While my least favorites are Kanto and Johto region. It's very ironic considering I started from Gen I at the age of 6/7 as I have been saying from my other posts. It's just difficult to get engage with Kanto because of its boring land, boring plot and boring villain team. The fandom's love for Generation I didn't make it better, instead it's sour and bitter towards the said generation and region. The Kanto remakes are really my breaking point, that moment was 'I had enough, that's it'.
Johto is my second least favorite since it shares a lot of Pokémon from the Kanto region (and even the league), it feels particularly worse when Gen II Pokémon are almost no where to be seen in the Johto based games. Though the dislike isn't as intense as my dislike for the Kanto region.
