I have two OLED Vitas, a beat up one I used for 10 years and a gently used complete in box I imported from Japan. I prefer the LCD, and have for several years. However this is only a recent development (3-4 years) when I noticed the LCD at max brightness was significantly better in bright conditions than the OLED was. I've checked some of my friend's OLED Vitas too, and none of them are nearly as good as they were in the old days. The hue shift on some of the screens is pretty noticeable.

Looking back the old screen was awesome. Going forward I think the LCD Vitas will be a better pick.
