Burn-out probably depends on the model, not a lottery, but shouldn't be a major concern for typical usage patterns in recent models. The text issue is caused by a pentile subpixel layout which are no longer common. I love OLED for low-light evening usage because IPS displays always have some backlight bleed, whereas OLEDs can display true blacks/pure warm tones which I find much more pleasant in the evenings. IMO power consumption is the only major downside of OLED displays for general-purpose laptops and phones.
