Apps that are good to install as system applications?

[Soundtrack to Chaos]

Does anyone know what apps are good to have installed as system apps?

I know that not every app should be installed as a system app obviously, but there are some apps that basically say they do more as a system app and work better installed as a system app, then they do regularly, for instance, brightness app lux, when installed as a system app, manages your brightness and is activated once your device is turned on, and also, when you kill the app via your recent apps manager, it continues to work

So what apps do you guys have installed as system apps, and which apps are good to have as system apps?

Thanks

I have Cerberus installed as a system app. Has more functionality than it would otherwise.

Going to get that app one day, it's actually in my Google play wishlist, lol

Its a great app, I've used quite a few security apps but Cerberus is my favorite. Its one of those apps that you'd rather have sooner than later though lol. Be hard to install it after the phone has already been lost.

I have cerberus. I had it installed as a system app but had to revert as it blocked the ability to be recognized by my pc. Great security app though.
