Valorant roles

Which type of player is most valuable for competition? The specialist who only knows how to play one role or a flex player who doesn't play a specific role so well, but can play different roles?
I personally prefer specialists, I would like to see Demon1 improving Neon/Raze and becoming a full duelist instead of him playing Jett/Controller

historically speaking specialists are the most important

specialists turn mid teams into good teams
flex players turn good teams into great teams
great specialists turn great teams into champions

I like the Jett/Chamber players though

1 good flex and 1 good specialist will make any team better
