Exactly. THIS on bold is the perfect description for STUTTERING or LAG. So if really know what is stuttering, I just don't understand why you was "faking" you don't.
If LCD black is brilliant for your eyes, good for you. But it's impossible to compare with ANY OLED specially in this particular aspect. The difference is HUUUUUUUUUUUUUUUUUUUUUUUUGE. After all, the black on LCD is just grey, not black AT ALL. Even the bests LCD displays have grey blacks. Just google for further information.
About battery life, it's not my opinion. LCD have to be 100% on. All the time. OLED not, only the pixels that are requested. Google it for further information. Again.
I forget to mention about the OLED superiority on viewing angle too. LCD have a INCOMPARABLE worst viewing angle technology EVER. Even older techonology (like de 80's TV displays) are much better. The IPS technology minimizes a lot this problem, but it's not perfect. Still pretty bad. OLEDs displays are far.. very, very, very FAR superior.
If you don't know, LCD backlight is an outdated technology, while OLED... Well, if you find a new LCD TV for sale, let me know... The only reason for LCD screens still there on smartphones is because it is a VERY cheap technology.
