A314 is the most expensive because it is truly AD’s flagship product and one that many famous faces purchase even. It gives the leadership vibe where people will look to you for advice, model your behavior as you are with them, maybe even mimic your laugh, and you will get all that respect. Its the best for work environments especially if you are looking to climb the inner ladder. Just know that it may produce more work on your shoulders since people will expect you to know the answer to this or seek advice on that, etc.
It is also like the others said kinda serious but can be toned down with a social like instant shine or instant honesty. At too high a dose straight you can be too intimidating and people will avoid you or distance themselves from you.
