Nashville or Scottsdale for Bach Trip?

I am really torn between going to Nashville and Scottsdale for my Bach Trip for the end of October. We are from FL. I need help deciding! Would love advice/things to do

Nashville would be more of staying in an airbnb closer to Franklin and just going into Nashville for one crazy fun day/night and then the next day renting SXS through country back roads to wineries. The airbnb has a pool, cute outdoor area, it's up a hill so there's somewhat of a view, and enough beds for everyone. I love the honky tonk cowgirl vibes, but most of my friends have been there before.

Scottsdale would be similar. Pools days, SXS rental through desert, maybe some hiking trails, and rooftop bars/dinners, maybe some shopping/cowgirl hat bar? I love how its different than what we are used to and none of my friends have been there before.

My other friend has her bach trip 2 months before mine and decided to also do TN/NC area after she knew I wanted to do Nashville for mine so that kind of screwed me (long story). I've always leaned towards Nashville until the idea of Scottsdale came up.

(Please don't comment negatively about going on a bach trip, my friends all want to go on a trip.)
