Emulators > Source if you have the experience to seriously develop a fully working, professional emulator.
Sorry but, there's never gonna be a time where we know the official source inside out, but if you made an emulator, you'd know exactly where everything is, exactly how to change xyz. Therefore yes, it's much better. But yeah it's finding someone professional and with the experience to do something like that.
Around here, just not gonna happen.
