I also own Gigabyte AERO 15 OLED laptop and I must admit I prefer this screen over Apple's. White text on black looks amazing and to be honest feels a bit magical, like a thing floating in the air, especially if I look on this screen in a dark room. Code, terminal content looks amazing. It's only 60Hz though, but for mostly static coding 60Hz is enough. Ubuntu works really well, so I don't have to deal with Windows for programming work if I don't have to.
I'm tempted to buy LG OLED 27EP950, it's expensive, but honestly I'd pay those money to reproduce Gigabyte AERO 15 OLED experience on 27 screen. But I know it won't happen, because LG screen will have worse pixel density, it's only 4K. It should be 5K at least, or even 5.5K or even 6K.
