[@Lunar Templar]On your opinion, do you think the RG models would have a much stronger performance compared to simple HG?

as pop said, due to the level of detail and attention required for even a straight build, I would say yes.

there's the inner skeleton like the MG and PGs, the level of articulation, and just the level of detail they come with out of the box.

though modern HGs are rather good as well now. Dark Matter/Amazing Exia for example has a 'partial' skeleton you build on.
