Both are okay, but there are some exagerrated points on the Denix replicas of both models (i.e. 92F lanyard ring too big on Denix, Python rear sight too vertical on Denix), and the fact there are no Colt or P. Beretta rollmarks on the Denix'... depends really on how accurate you want them to look on display...
By the same token, you can find some really good looking heavyweight airsoft versions that are more accurate down to the factory trademarks...
That and you can chase the cat or dog around the house with the airsoft... :lol
