It is not a good idea to do this unless you are happy to risk breakage or need the very latest kernel/firmware for a reason. Firmware updates and Kernels are packaged when considered safe/stable to be updated via sudo apt-get update; sudo apt-get dist-upgrade.

Even on Raspbian you should only use this with a good reason.

This gets you the latest bleeding edge kernel/firmware. There is always the possibility of regressions.

Bug fixes and improvements will eventually make their way into new Raspbian releases and apt-get when they are considered sufficiently well tested.

A good reason for using this would be if you like to help with the testing effort, and are happy to risk breakages and submit bug reports. These testers are welcome.

Also if you are suffering from a bug in current firmware (perhaps as one of the reporters of the bug on github or forum) and a fix has been pushed out for testing, then using rpi-update is the right way to get the fix until it makes its way into new Raspbian images and apt-get.

Backing up before updating is always advisable.

Well you're right, the update ist only usefull, if you run into issues.
Luckily it's not a real "Firmware" flash. This updater provides automatic backup boot.bak - so you can easily make changes revert.

Thank you anyway @BuZz for your suggestions :)

Yeah, don't do this. People have enough problems as it is.
