AFAIK the tubeless sealant is more reliable, I'd guess because a thicker tire allows more depth for the sealant to fill vs a thin tube. I've found Mr Tuffy great vs glass but it might be vulnerable to big thorns or frequent tire wires. Plus tubeless is supposed to eliminate pinch flats which seem possible on rough tracks. I'd use wide tubeless tires & preferably a suspension MTB too. A lot of even dirt roads in Mexico are pretty good but conditions can vary wildly.
