Gen III is not great. Shedinja is a gimmick, and every other final stage either got a mega evolution or a straight-up evolution one generation later...which stands out.

Gen IV has some solid options, but Dusknoir is too little, too late, and Giratina sucks.

Gen V at least tried to do something new with their Pokemon, introducing three new type combos. Not my cup of tea though.

Gen II is solid, but there's only one Pokemon on the list.

Gen VIII against has the same problem is always has...too much monotype bullshit. Sinistea/Polteageist/Corsola/Cursola are all pointless additions that could have been something better. The Hisuian forms are solid though, and Spectrier is great, plus Dragapult is solid.

Gen VI has good megas, and Aegislash's whole line is solid, plus Gourgeist is fun for what is it. Phantump's line feels pointless though, and Gourgeist isn't THAT good.

Gen IX has some high-tier Pokemon like Ceruledge, Annihilape and Flutter Mane, plus fun gimmicks like Gimmighoul and Gholdengo...but Bramblin/Brambleghast and Greavard/Houndstone (which shouldn't be mono-types) bring it down.

Gen VII is solid with Marowak, Decidueye, Oricorio, Mimikyu...and then they fill up too much of the roster with stuff I don't care as much for.

Gen I is perfect, but there are only three options.
