If people say that, they don't know much about the product. The two tires are very different internally, and about the only thing similar on them IS the tweaked tread pattern.
The original LTX M/S is mostly rated either 500/A/B or 440/A/B depending on the size. None of the LTX M/S has Michelin's Green X certification either. In comparison, the new LTX M/S2 are rated 720/A/A. This is a huge increase in expected tread life, and importantly (for some), an A rating for temperature. This is pretty much unheard of for light truck tires (especially ones with a T speed rating). This adds a safety factor for highway use not found in other light truck tires. An A rating for temperature is one reason many people like to use H-rated tires or above. The M/S2 brings that additional safety net to a T-rated light truck tire. Again, unheard of in this market segment.
The new M/S2 is demonstrably a better product than the original M/S, as good as those already were. Anyone who claims that they're essentially the same tire clearly doesn't know the product.
