Which is the best, ".xx" or ".com.xx" in general and for SEO?

[NachoRetta]

Hi, I'm working for a digital marketing agency and have traffic from different countries. We are planning to make different websites for each country. What is the best SEO practice to choose the domain between ".xx" or ".com.xx" from Spain, Mexico, Chile, Colombia and Peru?
I think that the ccTLD is better always, for example ".es" better than ".com.es"

I don't know that it much matters. The localization signal from just the ccTLD is not terribly strong but it should be the same for both the older .com.xx as well as the newer .xx

For purely aesthetic reasons I would choose .xx
