Espeon

Each player who competes for gyms should eat snorlax with a bit of patience. Yes, i am able to kill them too.

The actual challenge is called "Blissey". Dodging her quick attacks will probabely lead to time-out.

I barely killed a Snorlax of 1800 with a Skarmory 1143.

I tell you something Skarmory... that shiet is not bad at all dude.. perfect prestiger against Exeg........

Killing Snorlaxes in a row is fairly easy for now if you fill the squad with the big 7, plus Ursaring, Espeon, Golem and Exeggutor.

killed 2 laxes with. a cp of 2.8k and 3k using a 1.8k vape ? if youve been playing this game for so long you can ( playing and understanding the game mechanics ) dodge it all

Espeon has the highest attack stat of all the currently available eeveelutions. It is also currently the highest CP psychic Pokemon. It has a low stamina stat though (same as Flareon and Jolteon, half of Vaporeon).
This video is a comparison of all the Eeveelutions.

Snorlax isn't difficult to defeat. Pretty much all Pokemon all easy to defeat except for blissey. Someone did the calculation to come up with a defender quotient and a pound/psychic blissey was worth 2 ZH/HB snorlaxes and a ZH/DZ was worth 3 snorlaxes of equal level.
