>>33194194Gen 6 is tolerable and has a few perfect designs (Pangoro, Klefki, Xerneas, etc.), but also has a lot of truly hideous Pokémon (the shitty squid line, Aromatisse, Slurpuff, Zygarde, every one of the mythicals, etc.)
Gen 7 has the worst designs in the franchise's history (though Salandit, Mimikyu, and Pyukumuku are all great, and a lot of the alolan forms are pretty good), and it has the highest density of ugly, awkward, or bland Pokémon: Lycanrock midnight, the the entire seal starter line, Salazzle, all of the Oricorio forms, Ribombee, Lurantis, the Mudbray line, the lychee waifumons, the retarded crab line that starts out as a boxer and turns into a snowman for some reason, Drampa, that hideous fish with people lips, that awful alien mushroom thing, Type Null and Sylvally (which are two different Pokémon for no reason), all the Ultra Beasts, and all the legendaries (minus Marshadow) -- all of these designs are just awful. Adding to this, gen 7 has the highest relative amount of anthropomorphic Pokémon of all the gens, and the most waifubait mons.
Gen 7 is the worst designed gen, and I think it's because the designers finally realized they weren't at all constrained by sprite art -- even in gen 6 where they started experimenting with ridiculous proportions and details, it still seemed like the team was reined in by the ghost of past limitations. By the second sprite-less generation, I think the designers became totally aware that they had no limitations, and so we're left with all these hideous, retarded designs.
