Some photos of United Warpath, Thunderwing and Windcharger with Hasbro release comparisons.

Unlike previous Hasbro vs Japanese releases there is very little differences between the two versions including the infamous Hasbro grey. Warpath has the most difference but it's only due to the shade of maroon now being closer to the G1 toy. Despite this, I prefer Generations Warpath colors better than United.

As Takara-Tomy has become more 'mainstream' in recent releases, they appear to steadily resemble Hasbro's instead of having that higher quality feel about them. If this continues, I project that by the end of the year, Japanese releases are likely going to be on par with Hasbro releases; they will no longer have that 'Premium' feel about them.
