A few weeks ago a Twitter user made a poll asking people to pick any and all Pokemon they like for each region and I thought the results were interesting. Note that this isn't about which Pokemon is the most popular in their generation, but which ones are the most widely liked.
I'll post the Top 3 most and least liked Pokemon for convenience:
>KantoBulbasaur, Arcanine, Gengar - Most
Raticate, Drowzee, Kakuna/Goldeen (tie) - Least
>JohtoUmbreon, Espeon, Ampharos
Igglybuff, Granbull, Snubbull
>HoennMetagross, Flygon/Gardevoir, Mudkip
Illumine, Volbeat, Cascoon/Luvdisc
>SinnohGarchomp, Empoleon, Luxrai (Lucario is 4th)
Burmy, Wormadam, Bibarel
>UnovaChandelure, Krookodile, Volcarona/Galvantula
Patrat, Watchog, Basculin
>KalosAegislash, Greninja, Noivern
Aromatisse, Binacle, Bergmite
>AlolaMimikyu, Rowlet, Primarina/Decidueye (tie)
Gumshoos, Yungoos, Trumbeak
If you want to see the full results, I posted them on this Imgur link
