my 2 cents: depends on the tech inside. most of the good gaming monitors will have better response times (when tv start from 20ms). i can say, i wouldnt notice a difference between 4, 20 or 50ms response time. most monitors for gaming will have more hz!
id like to play on a better screen as well (doesnt matter if console or computer)! but i sure never wanna play sitting in an office chair, at a desk, looking at 32inch max!!!! NEVER EVER AGAIN!!
i really do like a bigger picture and i really do like sitting in a comfy armchair. well, might be some users have armchais in front of their office desk... but i dont know anyone who does!

anyway, i have no office, no office desk... so i use my TV.
its the comfort part that i like a lot!
ps: hooked my new computer to my 55inch TV too! 55"/4k/60/hdr... all good here!

pps: and i have the feeling, that this gen is finally using my TV (wich i bought in 2017) to the full potential. finally. so no need to by a new one. this is roughly planned for the PS6 (i tend to own a TV for around 10 years) and makes more sense for me!
