MAX: best shape and pretty but it will break even without playing. The alloy is fragile and the paint is weak. The paint will break with time esp. ver 1. The joints are only smoother but the material has not been changed at all.
CMS DX: Biggest GGGG but it is deficit in weapons and the final fusion is not complete.
CMS Brave: Full weapons but the hip joints can't tolerate the body weight. The range of movement is limited.
GFG:
MAX: nil
Kotobukiya: All joints are made of PVC only and they will also break after displaying. ( I have two broken displayed GFG.
CMS: Full weapons and near total Final fusion.
Takara: Largest GFG but the final fusion is only partial. Interchanging parts are needed.
Range of movement is even worser than CMS
SHE: Smallest but most expensive ( GFG + Goldion Hammer would cost your ~$9K!) 100% FINAL FUSION and full weapons.
It should be the best GFG.
GGG:
MAX: nil
CMS:
Full weapon and 100% final fusion
Takara: largest but the worst shape. Only partial final fusion
