Arctis 3 or 5?

I’m looking to buy a new headset and am wondering whether to buy the Arctis 3 or 5. Obviously the 5 is the later model but I’ve heard that the stereo sounds in the Arctis 3 sounds better than the surround sound in the 5’s. I’ve also heard that they have the same mic. I literally couldn’t care less about the RGB and the price difference is only $20 which isn’t that big a deal. Any recommendations on what to get?
