Same price as the C5 77 but the main issue is the ongoing issues with input lag/HDR with the C5. I opted for the G5.
Made this post so people can make an informed decision/comparison.
Rtings comparison post HDR fix
Both reviews mention the HDR issues but updated video suggests G5 is fixed and only partial fix for C5
Those who are looking for 77", price match could be done with Videopro and Perk discount on top bringing down to $5,098
