Bruxish

Its utility matches its aesthetic beauty. That is to say it's a flamboyant but ultimately unattractive option for... basically anything. It has a great Defensive moveset, but it's little more than a speed-bump on that front.

Best PvE Offensive Moveset

• Confusion and Psychic Fangs or Water Gun and Aqua Tail are the best options here.
• Bite and Crunch are sub-par.

Best PvE Defensive Moveset

• Confusion is the defensive Fast Move of choice.
• Water Gun and Bite are sub-par, but they both have their defensive utility for working against specific counters.
• Crunch will tend to be the best Charged Move option, though Aqua Tail is great tooo.
• Psychic Fangs is pretty weak.

Confusion deals more damage than Water Gun, but Water Gun's far speedier duration and different coverage can be useful. Bite is a rather poor Fast Attack, but may find a niche in certain cups.

Psychic Fangs is Bruxish's bread and butter, amplifying its already potent Fast Attack pressure. Aqua Tail is another cheap STAB option and provides good coverage with Bruxish's strong Psychic-type attacks. Crunch is a valid option to smash opposing Psychic and Ghost-type Pokemon.
