I've also looked up what people used for their G75 laptops and results are similar. I travel often so the checkpoint friendly ones have the upper hand at the moment. I am also aware that the new Asus RoG backpack is coming out but not sure when.
I almost in the same dilemma. I have the Everki Titan which I needed to transport the Alienware m18x R1(sold) I had. Then I used it for the Alienware m14x R2 (will be sold at the moment) and now I have the Asus G750JX. I see the G750 depth is already on the limit in the Titan.
I need a slightly smaller backpack, but the G750 should fit anyway. An Alienware backpack is not an option (if you don't own one).
I've read that the Everki Beacon can fit a G75 in the laptop compartment just barely (very tight fit). But looking at the dimensions, the G75 is 16.30 x 12.60 x 0.90 inches and the G750 is 17.30 x 12.50 x 0.70 inches. So the G750 is a little narrower and thinner but an inch longer, meaning that the Beacon may be a good choice. I'm leaning towards the TItan for its checkpoint friendly feature though.
The Everki Titan is really pricey too looking at it, nice bag though but I wouldn't say it's multi-purpose. I use my Swissgear on University trips all the time, with a cheap laptop, 2 extra batteries and all my hiking gear too. Works a charm 😛
