I love my MX518. I've used a G5 before, but the only (really) annoying thing I don't like about the G5 is the tilt scroll wheel. I use the scroll wheel to switch weapons sometimes in Q3.
I've also used a Razer Diamondback. But the cord got a short in it and kept losing connection so I had to switch to an MX518, replace the Diamondback. However, I found it was really hard to get used to the Diamondback again after using the MX518. However, with the Diamondback, I could rail in Q3 really well.
