What u prefer vellenato or bachata??

I looove Bachata. I am not quite sure what vellenato is. If it is the type of music that Fonseca and Fanny Lu sing than I like it. But when I looked on Youtube the songs that I heard sounded more like Mexican music. Now don't get me wrong I am half Mexican but I can not stand Mexican music so if it was what I saw on youtube than I do not like it. Anyways, I especially love Aventura's music that really hits me where it hurts.
