>>8424187aesthetically, i'd say all Fewture devilman figures are worth it because i love nirasawa's designs. they're older figures though, so articulation isn't very good.
for ones that mix more modern designs and articulation check out either of the following ( although people have had issues about durability or build quality with either ):
Sentinel's Amon comes in a standard red version and a white version with a skeletal face.
Megahouse's Variable Action Hero Devilman comes in standard green version and a tan skin version that resembles his more traditional/OVA appearance. this one was also designed by nirasawa.
