(maybe this is an apples against oranges comparison - but have R&D costs, customer expectations changed so much.)
Does oled now have same maturity as plasma did, and the folks with the Panasonic/Pioneer plasmas are still running with those.
started selling plasma in 2000's and they were reliable by 2005 ? folks were paying in the >£1500 domain, so with inflation perhaps more expensive than oled now
That is where the build quality comes in, although the Sonys have good technology, recently saw this
impressive sony tech review
The Sony name is tarnished, for me, with the failing pcb boards (they dropped the ball, maybe the new CEO is fixing it), I do not remember a similar panasonic incident.
The above article does re-iterate that if you are not viewing in blackout, the oled blacks may be of less interest and that higher nits are of benefit (I never view in blackout)
However I want (have had) 7 years usage so I would invest in Panasonic, however not ready to drop £2k so would probably consider the updated version of their
led 902, rather than oled - currently mid-term with 1080p IPS et60 panasonic.
