Getting 3 32" 4k monitors is still better than having a single point of failure. But also I'm extremely happy with my single Odyssey G9 55".
I bought a 30" monitor back in 2008 when that constituted a large monitor. It had a 12 month warranty and died after 13 months. :-(
I switched to 2 24-inch monitors which cost less, had more total pixels, and most importantly I no longer had that single point of failure.
