Happy to answer any questions, I've not noticed any of the drawbacks mentioned with the Alienware. No issues with coating, no issues with packaging, there's no fans fitted, I've not noticed any coil whine, can deliver full resolution and frame rate without compromise, I didn't even notice any issues with text (which was my major concern given all the press it gets) but besides a few websites which looked like they lacked anti-aliasing I've had zero issues in that regard and BCTT cleaned up the few places there were any issues.
The bundled stand isn't great, it works fine but is not stable. Full sized video connectors would have been nice but this is a preference rather than a problem. I would have preferred it didn't behave like a Smart TV but some may view this as a benefit if they intend to use it for things other than just as a computer display. I haven't calibrated it but I'm very happy with how it looks in desktop and especially in HDR games. This replaced a LG 38GL950G which means I lost 4" and it's 1600 vs 1440 resolution but otherwise I'm very happy with the change.
It is more expensive than the DWF but I came to really dislike the fan in my old monitor so I would happily pay the extra to avoid fans but that's probably bad advice for anyone not sensitive to minor fan noise. After going through my usual process of overthinking an upgrade I'm of the view it's probably a bad time to buy a new monitor, it looks like there's lots of interesting new screens coming out.
