For native spanish speakers, how good was Nacho’s spanish?

I was just wondering because I looked him up and apparently he has some mexican roots, and that he claims to be fluent in spanish, but for some reason I feel like they tried as much as possible for him not to have spanish speaking lines throughout the series.

I don’t speak a lick of spanish though lol, so I want to ask the peeps that do whether or not he sounds good or is really fluent?
