It's slightly faster, in that it would perform better in low light.
It'd make little difference tbh unless you're a pro. The 1.8 is a genuine bargain, and you may as well get one new - I've yet to see a bargain used lens on eBay. And I've looked obsessively for about 2 years
Camera bodies are a different matter - bought both my cameras from the 'bay.
