Will you root given Marshmellow will do app data backup? (Poll included)

I've been rooting devices since my first android device. And using Titanium Backup, to always restore my app data across devices. Or restoring Nandroid backups at times. But it seems with that, upgrades to new OS have become more of a hassle. Since I can not simply let the OTA apply its self.

Having to change to stock recovery depending on the device and in some more recent cases, having to wipe data for the update to go well. It has become a bit of a pain, harder than it used to be.

With Marshmellow doing app data backup. I'm going to try keeping things virgin, no rooting. I may not need to continue with Titanium Backup and since OTAs will work flawlessly, I won't have much personal need to get into the system file area.

So what about you? Respond to the poll and give your take :) .
