Personally, mine is joint first between Sandshrew (the cutest), Espurr (most relatable), and Gastrodon.
After those, in no particular order, I like Turtwig (best starter, fight me), the Roggenrola line (little rock guys), the Litwick line (candles and lamps with nefarious intentions), and Metagross (cool robot thing).
Kyogre is the best legendary in my opinion
Psyduck and Gengar
Good picks! After Sandshrew, Psyduck is definitely one of my favourites Kanto mons. Gengar is also high up there!
Metagross. He’s hits like a genius freight train.
also one of my faves, but wish I could sit on him:

Trubbish.
He’s just a derpy lil bag of trash.
I do not like his evolution, though.
Nidorina.
It’s one of the first Pokémon in gen 1 that isn’t recognisable as another creature. It feels like the first ‘monster’ you really run into.
I also caught one early in my first playthrough, and didn’t find out about the moon stone evo until very late game. I just thought that Nidorina was the final form. By the time I learnt, I was kind of attached to the middle form.
Snorlax, dude wakes up just to kick your ass then goes back to sleep.
My favorites are Torchic and Blaziken. Pokemon Saphire was one of the first video games I ever purchased, and he stuck with me through a lot.
I hate how TPC has repeatedly done the evo line dirty by overriding them with multiple fire/fighting type starters with higher stats
Probably a bit basic but Charizard and Umbreon. I like ditto and wooper too! Though my favourite starter is either totodile or cyndaquil depending on the day lol.
Wooper is such a vibe
Vaporeon
Cofagrigus is my son

Back when I was really into Pokemon I liked Dewott. After not playing Pokemon for several years, I think Pikachu became my favorite; it’s really the only pokemon you get exposed to if you don’t play the games and the design is very iconic.
About a year ago I played Cobblemon (Minecraft Pokemon) and Joltik / Galvantula became my new favorite. 🕷️Eevee > Glaceon and Sylveon, Charcadet > Armarouge and Ceruledge, and I also like Genesect.
I think it’s fair to pick a few with how many there are now.

Mega Lucario would be my pick, followed by Xerneas.
From the first game boy games I rolled a lot with Charichard and Nidoking, then did not play untill like a few years back and ran into Grimmsnarl and that is my favourite of the new ones.
Jolteon.
