I have all 5 SRCS and I think Daizyujin and Dekaranger Robo certainly the best and most accurately represents how mecha look in the show.

I really think it was a bit of a learning curve. While all are great figures, Gokaioh and Shinkenoh are a lot lankier then they should be, particularly Gokaioh and Magiking is awesome but very stylized, almost to Retrofire levels. Dekaranger Robo and Daizyujin are when they really got the idea merging the suits with highly articulated figures right.

Gokaioh, Magiking and Dekaranger Robo are notable for having an absolutely awesome set of accessories though.
