Differences between Hasbro Re-Issues and Takara TF Collection Re-Issues?

What , if any, are the differences between these 2 lines?
Do they use the same molds?
Color schemes/stickers?
Articulation/joints?
Material (i.e. plastic/diecast)?
Also, how different are the re-issues from the original G1 line?
Thanks
