Tarantula doesn't have backlit keys neither does the 7G.. There's only G15 for you I guess. Don't know about the comfort when typing. I chose the tarantula because it doesn't have backlit keys.. Don't like so much bling bling. The keys are good but need getting used to. It is a wee bit overpriced IMO.
PS: Wait for the gaming gods to respond. I'm just a humble TF2 player
Eazy Sir has the same. He loves the rubber finish but one of my friends who plays quite a lot decided to sell it and go in for a G15 as the rubber finish was starting to come off..
I like the key touch and the back lighting but wish it could have been a bit brighter to view in daytime, though at night the LED brightness is very good.
I do not play games so I am sure the rubber top of the keys will last for a long time.
