Trolling, right? -__-
Mexican and Venezuelan spanish are the most neutral ones, that's why they are the countries where most programs are dubbed from English to Spanish in Latin America. That's a fact.
The fact that many Mexicans imitate North Americans doesn't make them speak Spanglish =/
The "z" and "c" pronunciations from Spain is not actually what makes them speak horrible. They are just lazy pronouncing correctly and you just hear them blabber and occassionally pronouncing strong "G" sounds. "¡Joder, bhsbhshshshsa J hshs J me cago en la puta madre!". That's how a person from Spains speaks.
I like English a lot, especially the Brittish accent. It just sounds smooth and classsy, while Spanish is harsh and some words are awkward, lol.
And yeah, Italian is cool, but, definitely, the best language is Esperanto!
Also, I'm Mexican.
Lol is funny when you hear how you language sounds from the mouth of a foreigner
it depends from the part, I am sure your country have accents too, chilango, chihuahua etc. In Spain there are many different accents aswell depending on where you go. If you go to the south people would skip consonants when they come as last letter of a word, if you go to the center they pronunce S but they say "la dije" instead of "le dije" when they talk about a girl, which I find horrible 
. In the north-east people speak with a mixture of Portuguese-Spanish accent, and in the north-west a mixture of French-Spanish accent, in Canary Islands they have an accent that sounds a lot like Cuba or Puerto Rico, and they do pronunce C and Z like S, aswell as some peninsular cities like Sevilla, but is not the rule. Well I myself am from the South, and it's very hard for me to pronunce consonants when they are the last letter of a word, when I moved to UK I found it hard to pronunce things like "don't" (I keep saying Don') but now I'm used to it. 
BTW unrelated but funny:
