well i can speak up on behalf of the VFC version,
it's well constructed, feels like something that hasn't been made for $10 and sold for $80..
while i have yet to really use it in anger, it has survived a couple of games without having any issues.
best thing would be to see reviews on the net, but it's generally accepted that VFC is a brand that has a good reputation for build quality.
