Gen 1 Python vs Gen 2 is like comparing a vintage Corvette vs a 2020 model. If you want performance and durability... Get a 2020 model, if you a piece of art that is beautiful and great attention to detail but takes some extra maintenance at some point... Get an original.
Collectors want the history and work of art... Shooters want durability and bulletproof. Both have their place, hopefully the new one is going to be rock solid.
