This is my personal feedback so take it as such! I too love Samsung and was torn recently between Sony and Samsung for our upgrade to a new 55" 4K TV. Ultimately I went with a flat screen Sony, mainly for their better 4K upscaling and this model's better viewing angle. But again was almost a 50/50 coin toss.
My opinion on the
curved feature is that it is just hype. Only aesthetic value, nothing really gained as far as viewing. For now at least. Until we truly are at a point where we have over 100" television screens to where the curvature will make more sense to be in a more immersive and natural viewing experience. Also, I've looked and looked at the curved sets many times as I am very picky about glare. And for me, the biggest issue is the "smear" effect in reflections. While it all depends on the environment where the TV is located, this can be very distracting.
It's just a matter of optics and reflection. Every time I see a curved TV in a store (and yes, I fully appreciate that stores have way more lighting than a home) I always can see the reflection of the lighting on the surface of the TV screen smeared much wider than what it would be on a flat screen. And in some cases it almost looks like an 'infinite mirror" effect where you can see multiple reflections of the light source.
Ultimately, if you have a room where there is no light source behind you or off to the sides (and windows count as light sources!) then I'm sure it will be fine for you. For me with the TV against the far wall and a kitchen/dining room behind the couch in front of the TV, window and lamp to the right...no way curved.
Not saying this site knows it all but a very good example of what I am referring to can be found further down the page:

Good luck!
