Personal opinion. If you need someone that is gentler, then Sass is great. If you need someone to really work hard on your muscles then Vazquez. I see them both.
Another vote for Dr. Vazquez at Chirofirst! (Haven't been adjusted by Dr. Sass but he seems like a really good dude.)
I see so much love on here for Cliff Walker but I have to say that I'm not a fan. Went to him because of all the recommendations but came away feeling worse after he adjusted me a few times. Going to him seems like you're going back in time to see a chiropractor from the 90's. He does no muscle warm up or soft tissue work, and little if any assessment during the first visit.
Depends what you are needing done. I've used Dr. Cashion at BCS for routine adjustments for years, Dr. Walker when Cashion is out. Not a fan or Dr. Rio. They also have some good massage therapists in their office.
The back surgeon recently referred me to Dr. Barnes for targetted treatment on my spinal separations. He worked miracles in a handful of visits. Enough so that surgery is off the table for now and I have not needed routine adjustments.
