Nothing really wrong with any of them. If they work for the studio, then that's all that matters.
I liked the S3A's better for my situation.
For reasons beyond my control, I didn't spend as much time with the other models as I did with the ADAMs.
The ADAMs weren't jsut perfect either (equal opportunity curmudgeon mode)

If you play the ADAMs right after the Mackies or something like that, you'll say 'Where did the bass go?' Sooner or later you'll hear it but it will be tight and it will sound good ... real good. I don't think I would buy these if you play a lot of booming rap music (of course they have a Subwoofer for sale, too).
Thes S3A just worked best for me in my situation.
FWIW, my brother in law has some Wilson Audio Watt Puppy 6 speakers and on closer inspection, I discovered I don't particularly care for how they sound....and they cost something like $22,000. The tweeters are the most tiring to listen to that I have ever heard. The mid range is over-hyped, too.
It's fun to bring mixes over to his house and listen to them, though!!!!
