If I end up decided to get one of them it'll completely depend on the version exclusives since your partner can't evolve.
Eevee. It's cuter, better base stats (in base form, since they won't be able to evolve), better ability, better z-move (though I doubt it will make an appearance), and I'm just tired of all the Pikachu emphasis. Then again, since it's really just a mix of Gen 1 and Pokémon Go, I might not even get the game.
Unfortunately the games are only going to have the first 151 Pokémon available, so Leafeon wouldn't be an option even if they could evolve. The first gen eeveelutions are kinda meh anyway. Except for Jolteon. And Flareon has admittedly grown on me a little bit, but not much.
For me it depends; I love both Pikachu and Eevee, but if this is kind of a sequel to Yellow... I might go Eevee, simply because I like Green (or Blue/Gary) better than Red.
Eevee, I just can't see Pikachu anymore, I mean it's literally everywhere. Also, Eevee has more Evolutions, and I like them more anyways.
Hard choice. Gotta say that I'm going to try and get both games, but if I don't then I'm going for Pikachu. I've liked Pikachu far longer than Eevee and I'm more likely to play co-op with someone that like Pikachu as well. Any Eevee I get I'm more likely to evolve than Pikachu Or at least if I get more than just Gen 1 Pokémon. even then I might be likely to evolve Eevee into Vaporeon at least. I still need to get Ultra Moon however, and I would like to have a phone that can run Pokémon Go now.
Eevee is better for a couple reasons 1: Eevee isn't as commercial or overused 2: Eeveelutions, 'nuff said 3: Eevee plush is very fluffy
Eevee. It's such a shame that Pikachu has become so iconic, because I want to like Pikachu, but it's freaking everywhere. If they could evolve, I think I would go for Pikachu, because Raichu is one of my favorite Pokémon. Seriously though, I kinda wish that these games had chosen two different Pokémon that are iconic in the Pokémon world, but not as overrated as Pikachu and Eevee. The ones that popped into my head were Abra and Gastly. Man, that would be so cool to have a psychic or ghost Pokémon as a starter.
I'm definitely choosing Eevee, mainly because Vaporeon is one of my favorite Pokémon in general lol. Although I do think Alolan Raichu is cute, I prefer Vaporeon more.
If you could evolve them there would be no contest, but without that option... idk honestly, it's a tossup.
Had I a choice between the two, I would've wanted both, and I probably would've defaulted to Eevee and left Pikachu to my brother. But when I found Let's Go Eevee just sitting there in a Goodwill for 30$, I knew my choice was clear. Eevee ftw!
A battle of the century. A little yellow mouse that I see everywhere, or a neat little fluffy cat fox rabbit thing. My pick lies in Eevee.
Theres a clear bias in the poll lol. Eevees my fav. It brought me back into Pokémon and well, for a while I thoughtPikachu wasn't that cute. Thats changed but I still prefer the cuddly little evolution fox to that thunder rat
