I would recommend the G9, mine was a recent model and reading online most of the issues seem to be overcome.
Every game I’ve tried works flawlessly, most of them look awesome in 32:9, I don’t play competitive games online so mostly it’s single player exploration type games with my favourites Far Cry 5, Assassin’s Creed Odyssey and Shadow of the Tomb Raider.
FC5 looks awesome, HDR works a treat, colors are so vibrant the full screen is alive. I’m playing it through again as it looks so bloody good on my G9
Yes, the experience isn’t perfect as the G9 firmware is not right as windows HDR looks washed out and awful but guessing they will fix this soon.
Performance is fine on my 3080, usually have everything maxed out at 240hz
