5.1.1 Root vs 6.0.1 non-Root

Like most, I like my phone rooted, with xposed and all the nice stuff roots comes with. Also it seems to make the Flex2 much more usable in regard of battery, adblock, runtime etc... BUT the MM update seems to be really good, too.

So, my question the people who have used both is:

What has the better overall experience ( battery runtime, performance, features, overall feeling ):
- 5.1.1 root with amplify / greenify / smart network / adblock
- 6.0.1 stock

Also, what are the alternatives for non-root regarding adblock in chrome?

Thanks & Greetz

SD card showing as corrupted on rooted MM (works fine on non-root phone)

As mentioned in the title, the SD card is showing as "corrupted" on my phone (MM, root). If I pop it in my wife's Note 4 (official firmware, non-root), it works just fine. So, there's absolutely nothing wrong with the card and I'm assuming that root is the culprit. Has anyone noticed a similar issue? If so, have you found a solution? Going the non-root route is not an option for me. Thanks in advance.
