Android rooting?

Is it worth rooting an Android or are you better off keeping it how it is?

I heard there's ways when you root Android to make the Samsung Galaxy S6 run way better than it does.

Don't use KingRoot on Samsung S6 it'll make your phone get stuck in a boot loop lol

Rooting has it's benefits, such as custom ROMs, apps etc. But if you use certain apps that require the stock OS to be not rooted, such as banking apps, Sky GO. Then they will not continue to work.
