Slightly less CPU usage ( audiodg.exe ), options for both, Rear & Side speakers for 5.1 setups, ability to manage Crossover ( on Enhancements -> Bass Management ) and ability to manage the volume of each speaker separately ( properties -> levels -> balance ). On an unrelated note, on Windows 8.1 the built-in driver seems extremely good. I hear the driver even for Z series on Win 8/8.1 have the same, ancient problems. I'd still be using my X-Fi Platinum while an order for a Z series would have been placed already. If only Creative could provide as good driver support. It doesn't give me option to select 5.1 with normal, Rear Speakers. which is problematic, at least on my Motherboard. Meanwhile, ASUS for some reason released the version 6. Both, Audio and Network always work flawlessly. Very good driver without a single problem so far.
