Which generation had the weakest set of Pokemon designs?

I'd go for either Gen 6 or Gen 9. As much as I love Sylveon, Froakie line, Flabebe line, Goomy & Goodra, Diancie, Tinkatink line, Spirgatito line, Flittle & Espathra, and Greavard & Houndstone, the legendaries and some of the paradox designs are cool as well. There were unfortunately many stinkers in the mix. like Delphox, Chesnaught, Diggersby (hideous), whatever the hell Aromatisse and Slurpuff were, Pumpakboo & Gorgeist, Klefki (one of the worst of all time) Pangoro (just ugly), and those dumb barnacle pokemon. Gen 9 had even more bad designs. Some off the top of my head were Palafin Hero (hideous), Scorvillian, Klawf (ugly), Whatever they did to Tentacool and Tentacruel (Why?!), Squakabilly, Flamigo, those two bulldogs (uglyyyy), Dondozo (hideous), Bombardier, and Orthworm (creepy). What Gen do you think had the worst/weakest designs? I'm genuinely curious to know everyone's opinion!
