in terms of the choice between a binaltech and alternator, i will choose a binaltech, which also is what i have now except, a hasbro silverstreak. that's because i'm not that interested in silverstreak and it also happens that there was a sale so i don't mind paying for it. otherwise, it's diecast all the way. it's the overall appearance and the weight that make you feel damn good while holding it in your hand. just like what zeo-mare says, imagine a chogokin without any sort of metal.
