Are 49'' monitors worth while?

For those of you who have used or switched to a 49'' monitor. How do they compare to your triple monitor setups?

I'm currently using a 27'' and 2 24'' monitors. They're fairly old with some bulky bezels but I'm hesitant to bin a bunch of working monitors to switch at excessive costs to something that may not provide a significant bump in utility.

I am also considered switching to some modern, small bezel 24'' 1920 x 1200 monitors, but they seem uncommon and overpriced.
