Thanks for your interest! The key difference is that Patcherex2 was designed from the ground up to be a highly modular binary patching framework. This makes it much easier to add support for new architectures and maintain compared to the original Patcherex, as many components can be shared across different targets, and patch implementations are mostly target-agnostic.
