Strangely enough my 18.5 inch Samsung monitor still works just fine after 7 years

Very good. Since the warranty for that is over, I suggest you get a spare just in case.

Don't know it's QC problem or electrical component problem with electronics nowadays. RMA-ed BenQ monitor twice and Acer monitor button problem.

I agree with you. Reliability and durability is generally based on the luck of the draw regardless TV or monitors.

just share my experience
few months ago i bought a sony 40inch tv and use it together with my dell 23inch as it's not syiok anymore watch movie on 23inch monitor
colour - if you use it for general use it's no difference
response time/input lag - TV is much slower than monitor but some TV have like below 20ms its not great but acceptable for gaming
reliability - same, it's all depends on luck..any brand will also break if unlucky..thru the years i lost count how many monitors and tv broken on me..electronis nowadays is like use and throw..nobody make things that last 10 years anymore like last time
to add:
pixel density - 1080p on 40inch tv text wont look as sharp compare to 23inch 1080p monitor, the bigger tv the worst
if you do alot text TV is not good unless go for those 4K tv, gaming depends what kinda games..but if like me abit of both of everything a tv is a good option or best of all use both together lol
I agree with all your points above.
I had the same experience with you. Once I use the huge TV screen for movies, I don't feel like watching movies on anything less than 40inch TV.
I think to add with the use of big TV, easier to have local multiplayer games such as Street Fighter series, Double Dragon Neon and etc.
