[Q] Stick with 4.4.4 or install 5.0.1 topic

Hello just a quick poll for Nexus 4 users. I've held off installing 5.0.1 as from scanning the threads it sounds too buggy. But thought I would canvas your opinions as to whether the problems are major or minor.

Keep in mind battery life is particularly important as I feel my battery drains too quickly as it is already.
