Funny how our perceptions differ: I fell in love with the PA3X after listening the latin styles, and especially the brazilian ones. The Bossa Nova style is a joy to my ears: finally a real bossa nova a la Jobim, smooth, laid back and relaxed the way it's meant to be.
And what about the sambas? There is even one that starts with a simple cavaquinho in variation 1 and then builds up gradually variation after variation, just like a real brazilian band would do.
If you fancy a cha cha cha I suggest that you buy or download the so called eBay styles: there are enough cha chas to keep you happy for a lifetime.
To sum up: to my ears the PA3X has the best latin styles among all the big three and -as far authenticity goes- I consider them on the same level as the Audya audio styles.
