Well 8.1 and 8.1.1 was definitely better than 8.0.2. Stability and bug fixes were noticeable. I have not make the jump to 8.1.2 yet as I don't purchase ringtones and 8.1.1 battery is stellar. But I would say go for it. Have read 8.1.2 was even more stable at least on the 6 series. If I was on 8.0.2 I would make the jump on my device. (iP6)
