The differences in terms of security, KEG of online-rotators:
When using online service rotators, you run them in your home browsers (and the system as a whole) in danger of
Some faucets that sinning opening multiple pop-up windows or redirect to other sites (unknown security, they can manage to install
something malicious in your system or browser, as long as you close page)
KEG, immediately blocks such action (does not even download these resources, ie even if they have some kind of malicious code, it will not be install)
At the same time on sites that show three or four pop-up windows, KEG blocks these pages, and still makes it possible to earn coins
