You really need to tell us what amplifier you have. The impedance/sensitivity ratings of all three models are different with the Arro being the most difficult to drive; the Sttaf being the easiest. Everything else you provided, won't matter if the amp is not up to the job first in properly driving a loudspeaker.
Next, the Arro and Sttaf use soft dome tweeters and the Hawk uses a metal one. Big difference in how they sound. One is not better than the other - it comes down to preference. So once we answer the amp question, suggest you audition all three models to find the one that sounds best to you.
