310 Manectric

Snarl is more favorable as its higher energy gains lets Manectric take advantage of its charge moves sooner. Charge Beam could be chosen if the extra STAB damage and Electric-type coverage is needed, but this is more situational. Thunder Fang provides a different style of play that focuses on damage output rather than energy gains, though this might be more niche. 

Wild Charge is the best Electric-type charge move in the game, costs the least amount of energy among Manectric's charge moves, and just makes Thunder redundant. Overheat is significantly stronger than Flame Burst, and provides some coverage should Electric-attacks be resisted. It should be noted that opting for both Wild Charge and Overheat makes Manectric extremely vulnerable due to their self-debuffs. Psychic Fangs can be chosen for its low energy cost, letting Manectric bait shields while also providing a debuff utility. 

Manectric is a very fragile and vulnerable mono-Electric Pokemon, and heavily relies on dealing huge damage with Wild Charge to be successful. The addition of Psychic Fangs following the September 2022 update is a massive gain for Manectric, not because it is a good Charge Move, but because of its low energy cost and debuff utility. Manectric now has the ability to constantly keep the opponent guessing whether the next Charge Move coming is a powerful Wild Charge or Psychic Fang bait. While this can be inconsistent, it's still a major improvement compared to its previous slow moveset. 

The level 50 update allows Manectric to use XL candy to reach the CP cap of Ultra League, which gives it more stats to improve its performance. Unfortunately its drawbacks with fragility and consistency still hold it back in Ultra League. Wins against opponents weak to Electric-type attacks like Water-types are not always guaranteed, which is disappointing for Manectric's role. 

Manectric would appreciate more stats to compete in Master League.
