I have looked over the stats for these Pokemon before, and coming from experience in building in all Eevee team, I know one thing when it comes to them. It's all in the moves.
There are some differences, speed, defenses, but what you really to figure out before you ask this question is what you want your Eevee to do for you.
In the end, as long as you're not restricted on the moves you can teach them, any would make a good choice. Either way, the articles on Bulbapedia will help you more there.
Each of the three original Eevee evolutions has areas in which it specializes. Vaporeon has the highest HP, Jolteon has the highest Speed, and Flareon has the highest Attack and Special Defense but the lowest Special Attack. They all have rather low Defense, though. When choosing which one to get I would pick the evolution with the type that best complements the types of Pokemon you already have in your party, (for example, if you have a lot of Grass types already I would recommend Vaporeon to defeat Fire, but if you already have a water and a fire type I would recommend Jolteon)
Or, you could replay the part of the game where you get an Eevee until you get one that is female (by saving beforehand and turning off without saving), and then use it to breed enough Eevees to get all of the evolutions.
All forms of Eevee are as follows; Eevee Jolteon Espeon Leafeon Vaporeon Flareon Umbreon Glaceon
Jolteon evolces using a thunderstone but if you give it a fire or a water stone it will evolve into a Flareon or a Vaporeon
The Seven evolutions of Eevee are: Flareon (Fire), Jolteon (Electric), Vaporeon (Water), Espeon (Phsycic), Umbreon (Dark), Leafeon (Only on Diamond Pearl and Platinum/ Enterna Forest Mossy Rock), and Glaceon (Same as Leafeon But on route 216-217/ Smooth Rock). PS: Eevee evolves into Glaceon and Leafeon only around the two rocks.
Theres a trainer on the bottom of route 214 , i think he's a collector. He has: Jolteon Lv24 Flareon Lv24 Vaporeon Lv24
Eevee has 5 evolutions in total. There are Umbreon, Espeon, Vaporeon, Jolteon, and Flareon. Firstly, is Umbreon, a Dark type pokemon, whihc can be obtained by gaining friendship with your Eevee when the clock is A.M. The second, Espeon, is a Psychic type, and can is gotten by gaining friendship with your Eevee when the game clock is P.M. The other 3 are considerably easier to obtain. Vaporeon, the Water type, is obtained with a Water Stone, Jolteon, the Electric type, with a Thunderstone, and Flareon, the Fire type Pokemon, with a Fire Stone.
Either a boy vaporeon,flareon,or jolteon and a girl vaporeon,flareon, or jolteon. Or breed it with a ditto
