Coming from my previous laptop (PC Specialist Octane/Clevo P775TM1-G) ,which was only about 3 years old, one of the first things that impressed me with the GP76 was the smaller size and weight of both the powerpack and the laptop itself. Funny that they were both negative points in your review. -so your impressions with this aspect will clearly depend on what you've transitioned from.
There is generally high praise for the responsive 360Hz screen, but in gaming use, I see no difference between it and my previous 144Hz screen. (I didn't actually want another FHD screen, but the price and all other specs were what I wanted so it was a trade off)
Finally, HWiNFO64 reports my screen as a Sharp SHP1544 LQ173M1JW08, not an AUO model as specified in your review; maybe a regional difference? -I bought my GP76 12UGS from a UK vendor.
