Culture of 19th and 20th Group

Hello,

I have been discussing with a 20th group recruiter out of Alabama and am going to join. I am from the West Coast and so is my wife. I think it would be more convenient logistically to be in 19th Group. Specifically, the one in California or Colorado if I am able. I know 19th Group is based in Utah. I have read that it is predominantly an LDS (Mormon) group with heavy influence in the Utah and Colorado state contingents / battalions. Is that true? If yes, how does that change the culture of 19th v 20th? How, for those in either group, do the cultures of 19th v 20th group differ? I know 19th covers SE Asia and 20th S America. Is the youtube video by valhalla vft "Special Forces Groups: Sterotypes of each group and the guys in them." accurate? Where does the 19th and 20th pull soldiers from active duty. All active duty regions so the culture is a mix or from one specific one?
