If you are looking for a large monitor primarily for playing games, or watching videos/movies, Netflix, etc. this might be a good value option depending on your needs. I got this on sale for $700 and for that price I feel like a got a pretty good bang for the buck. However, if you are planning to use this monitor for productivity like a work from home job it may not work out as well.
I had been looking for a monitor with decent, or good HDR either 1440p or 4k and this checked enough of the boxes that I decided to try it. I personally was looking for something around 32", but I got used to the 43" after about a week and now it feels really nice having the extra display real estate. The monitor can automatically resize windows to fit into multiple layouts allowing you to have a browser window open in a narrow space on the side of the monitor while you have a game or movie in a larger window on the other side allowing multi-tasking. You would think this multi tasking ability would carry over to be useful as a productivity monitor and maybe others would have a different experience, but I sometimes have trouble seeing the mouse cursor against light backgrounds and losing it on the screen with white backgrounds. There is also some ghosting when scrolling through text on a white background although it's not too bad to my eyes. This may not be an issue for others, but I could see it causing some headaches. I personally don't use it for this often, so it's a drawback I'm okay with living with.
On the subject of picture quality it really does look great in my opinion. HDR is plenty bright for me at 600nits and due to the ~360 local dimming zones it can produce deep blacks and bright whites on screen at the same time. However, keep in mind this is a 43" monitor and 360 zones isn't enough for great contrast in all content types just good. The smaller, curved variant of this same model the Odyssey Neo G7 32" (MSRP $1299) has around 1000 dimming zones on a smaller display which is going to give a better experience and might be worth considering on sale. Colors on this monitor are nice and vibrant and after some tinkering with settings have gotten a pretty nice looking picture that works for nearly all content it displays. If you are seriously considering this monitor it wouldn't be a bad idea to look at some examples on Youtube.
A last point that needs to be mentioned is the smart functions and how this affects the user experience. A typical PC monitor is just going to display what's coming from your PC, but this one behaves more like a smart TV and in my experience that is not necesarrily a good thing which I find to also be the case here. The display likes going back to the "home" screen when switching inputs and the controls, while faster than what I have on my home TVs, are still laggy and slow, and to be honest when I'm using this for a PC it's just much faster and easier to go to the Netflix website rather than try to navigate the Samsung menus. In general, I think having smart functionality on a monitor is just a waste and I have never had a smart display at any price point that had controls even as responsive as a cheap roku box. I actually feel like not having this at all and slightly improving the picture with the money they spent implementing this would have been a better investment. However, this did result in the inclusion of a remote to control the volume, adjust settings, etc and this is much better to me than using the buttons on the bottom like a normal monitor. The other thing you get from this is built in speakers that are actually pretty decent. If you have a nice soundbar or PC speakers already this is probably pointless for you, but this basically replaced my speaker setup and also allows this monitor to be used as a nice mid size TV, so I can see this continuing to get use after I switch to a different monitor as a TV in another room.
So overall I would recommend this to anyone looking to upgrade from a typical SDR monitor that either wants a bigger size, 4k, or maybe to use with a console as well. Since it comes with HDMI 2.1 it can be used with current gen consoles, PC, or for streaming video making it very versatile with good refresh rate and picture. If you can get it on sale (which seems to happen frequently with Samsung) it is good value at $700 for the quality you get.
