Which new Strixhaven is the fastest offensively

I only have enough money to buy one commander deck. I like decks that set up fast and are able to attack within a few turns and quickly become a threat. FF Cloud deck was great for this to me. In your opinion, which of the 5 is the fastest to get going and able to attack of the new sets?

And do you feel that's the overall strongest for a long match?

Thank you in advance
