Well for whatever it's worth I leave my phone on 24/7 365. I have experienced one slow down over the course I've owned my phone after installing an app. I rebooted the phone, this was 2 days ago, and haven't seen it since. I've used ATK too and ATK versus no ATK in MY experience in real world usage I saw no battery increase but did see about a 50mb memory increase. So until I actually need it I'm going to ignore it for now.
But I think some people seeing a battery increase may have an app that is not letting the phone sleep that stays running in the background, and ATK is shutting it down after you haven't used it in awhile. So all in all I think it mainly depends on what type of usage you are using your phone for and as normal YMMV.
