My favorite in order. (This is entirely my opinion) Imma list the problems in each gen and positives.
Gen 1: Bad: Full of glitches and extremely broken. Good: At least it was a good challenge.
Gen 6: Bad: WAY too easy that its a joke. Good: Mega evolution was pretty cool.
Gen 2: Bad: Has some pretty forgettable characters and recycled some thing out of gen 1. Good: Had some challenging battles like Red.
Gen 4: Bad: Was too slow and not alot of original pokemon. Good: Was actually harder than most of the main series pokemon games.
Gen 7: Bad: Slow, too much Japan only events, and pokemon are too slow. Good: Had cool pokemon designs and z-moves.
Gen 3: Bad: Water, the encounter rate was high, can't complete the pokedex (no mythical pokemon aren't needed to complete the pokedex) due to Ho-oh and Lugia being event exclusive unless you had some way to transfer them from gen 2. Good: Fun and challenging, the battle frontier, wireless communication was introduced, and legendaries were hard to get to and find.
Gen 5: Bad: So many bad designs for pokemon and karablast and shelment by itself. Good: The hardest and most fun games in the series, story was just right and didn't invade the game too much or too little, and so many pokemon to choose from.

Going from favorite to least favorite
>Gen 2:
Bad: Doesn't make enough use of the 'new' Johto native Pokemon. Most of them are out of the way and hard to find and most major trainers have Kanto Pokemon in their teams.
Good: Not a single bad design among the Johto mons
>Gen 4:
Bad: Not enough new Pokemon that aren't evolutions of older ones
Good: Fantastic region, best atmosphere in the series
>Gen 3:
Bad: Barely any postgame, even considering the battle frontier
Good: Lots of interesting side-areas to explore
>Gen 1:
Bad: Very few interesting environments in Kanto, bland region
Good: Fantastic Pokemon selection and generally decent designs
>Gen 6:
Bad: Not enough new Pokemon
Good: PSS was a great way to do online play
>Gen 7:
Bad: Ultra Beasts
Good: Good color pallets on most of the new Pokemon, mostly decent designs
>Gen 5:
Bad: Tons of terrible designs
Good: BW2 redeemed the gen

You literally have the exact same taste in Pokémon games as me. Gen 1 and gen 6 fucking suck while gen 3 and gen 5 are my two favorites

Add Gen 4 among the favorites and I think we can make a trio of people with the exact same opinion.
