I have not found that the Spanish-speaking congregation fits into any stereotypical box. They like "modern" music, although their "modern" includes folk-devotional pieces that sometimes date to the 18th century. They don't always dress up (and when they do, it can be LOUD), but they all kneel, on the floor.
The Carismaticos are into hand-raising and audible prayer, but they're also some of the strictest in morals and most knowledgeable about the Faith.
Personally, I'm prepared to be happy with whatever Pope Francis does.
