So i Have the K68 with Cherry Red switches, but at work we just got the Steel Series Apex 5 in. Im pretty tempted, I took it out of the box and the construction feels more solid than the K68. I play a lot of Call of Duty, The Witcher, Fallout, etc. Do you think the more clicky Apex 5, despite not being truly mechanical unit, is a better choice?
The construction on the SteelSeries keyboard is definitely better with the aluminium top plate. I'd ask you to try the switches out since switch preference will dictate how you live with that keyboard in the long run.
I'd pick the SteelSeries if I had a need for a full sized keyboard(I prefer TKL's).
