I have a monitor that's almost like this and it's surprisingly nice. It feels like a two-monitor setup. Two actual monitors would probably have been cheaper, but I got mine from work, so it wasn't a factor.
The real advantage of having two actual monitors is being able to flip one vertically for reading code.
Had an ultra wide for a while, went back to 2 27" monitors after 2 years. 2 monitors is more convenient imo. I can flip one vertical whenever. Less fiddly to have multiple things open at once. One is centered while the other is on the side and angled, much nicer way of separating what's my focus. Easier to screen share. I always found the curve distracting for text.
