TechnicalThe following table includes Espeon's base level for each stat, the range for each stat at level 50/100 with max EVS and the overall percentile. Minimum and maximum levels are calculated with 0 and 31 IVs respectively (ranges calculated with Veekun's calculator).
Like all other Eevee evolutions, Espeon is in the 80.7th percentile. Other Pokémon in the same tier include Dusknoir, Lucario, Venusaur and a few others. Espeon's best stats are SPECIAL ATTACK and SPEED, but is pretty average or lacking in the others. As a psychic-type, it is weak against DARK, GHOST and BUG moves, but resists damage from FIGHTING and PSYCHIC moves.
EVs, IVs & NaturesI just want to note before I start explaining my strategy for battling with Espeon that I am not a competitive battler by any means. If you are more interested in that kind of thing, feel free to head over to a site like Smogon University. If, however, you are okay reading my opinions, feel free to continue reading!
EV training was made much easier in X/Y and ORAS with the usage of Super Training. It can certainly be a tedious process, but for Pokémon that have poor or average stats, I have found it to be incredibly useful. My battle strategy with Pokémon that already have relatively high attack/special attack and speed is to hit hard and fast, so I would typically EV train Espeon for SPECIAL ATTACK and SPEED. That being said, however, Espeon does not have the best move pool to choose from and it is a little difficult to hit hard against opponents who are not weak against psychic-type moves. Espeon's defense is fairly low as well. Therefore, I max out SPECIAL ATTACK and split the remaining EVs between SPEED and DEFENSE.
Lastly, natures and personality characteristics are other aspects to keep in mind when choosing an Espeon for your team. Espeon's attack is so low and since most psychic moves are special attack, I would definitely choose a nature that lowers attack in favor of boosting another stat. Therefore, an Espeon with a MODEST (↑ special attack, ↓ attack), BOLD (↑ defense, ↓ attack) or TIMID (↑ speed, ↓ attack) nature would be the most useful in my opinion. Again, because I like to hit hard and fast, I would opt for a modest nature. If you are concerned with Espeon's defense, though, a bold nature might suit you better. Personality characteristics are the short description about your Pokémon that is listed with their stats. These are important because they serve as indicators of your Pokémon's highest IV. I am generally not picky about these, but I would prefer an Espeon with a characteristic for special attack. Highly curious, mischievous, thoroughly cunning, often lost in thought and finicky are all characteristics that indicate your Espeon's best IV is special attack.
Move SetEspeon learns the following moves in X/Y & ORAS by leveling up or through the heart scale move tutor (marked by a - in the level column). If you are looking for previous generation moves, TM/HM or regular move tutor moves, please check a site like Serebii or Veekun. Don't forget that Espeon gets STAB bonuses when using psychic-type moves and has much higher special attack than regular attack!

The last time that I used an Espeon in generation VI, I chose the moves PSYCHIC (psychic), SWIFT (normal), SHADOW BALL (ghost) and DAZZLING GLEAM (fairy). I like to have a variety of different move types in order to be better prepared to fight opponents that are not necessarily weak against psychic moves. Unfortunately, Eevee evolutions are a bit notorious for not having a large move pool to choose from, even when considering TMs and move tutors. Most moves you are able to choose from are psychic or normal. In past generations, I've used moves like Grass Knot (grass), Future Sight (psychic), and Hidden Power (depends on IVs) instead of Dazzling Gleam. If you are using Espeon in ORAS, a good move tutor attack to consider in order to counter dark types is Signal Beam!
