Are cigarettes in Mexico all that different from cigarettes in the US?

I live close to Mexico, my family has always gone there to buy cigarettes and other commodities, I smoke enough to buy a carton and I have wanted to buy one in Mexico. I've bought packs there before and they taste different (some lights are like reds) which is why I haven't bought a whole carton. But due to the fact that a carton costs like 15 bucks there and 40 in the US is too good of a deal. But I wondered is there a big difference quality or tobacco wise between cigarettes there and here? Is it worth paying extra to get cigarettes that are made in the US?

I finally went and bought a carton of Parliament Lights for 16 bucks, I think they're one of the only ones not made in Mexico, because the Marlboro Lights are kinda nasty, and have the government warning in Spanish, all the Parliaments say is Made for Central and Latin America, it also says Made In Neuchatel, Switzerland and they taste the same just with a different packaging
