As a quick message to people who haven't owned one yet, I own both and they ARE good keyboards, except the keys on my 6gv2 are starting to because "Shiny" (for use of a better word) and I got it for Christmas (as a gift to myself XDXD)
tl;dr
Keys get shiny FAST, buy replacement keys for WASD, if you are a gamer.
P.S should have mentioned I game a fair bit, bit 2 weeks is still too fast.
