Take this with a grain of salt since I haven't played competitively for a good while, but from being around people that do, I'd honestly say that moves that require charging/recharging are honestly the worst moves to go with. Reason being is obvious--you're giving your opponent a free set-up turn--and that turn in itself can decide the whole match. Idk if hyper beam is still used in RBY games, but I legitimately think that's the one exception where a recharging move should really ever be used.
Even in-game, I still find them to be fairly terrible. They get the job done, but so can literally any other move provided you're high enough of a level, without the inconvenience of having to wait an extra turn to make a move.
Moves like Draco Meteor, V-Create, and similar moves aren't as big of a deal because even if they "drastically lower" your respective stats, they can still deal a respectable amount of damage if executed more than once. It's not just once and your Pokemon is useless....I believe there are some Pokemon that can afford to "spam" moves like DM and Victini can spam V-Create under certain circumstances without much hindrance to it, so there's really not much of a disadvantage here, whether you use it in-game or competitively.
