This is a very good but complicated way. If you really just want to give 10 USD with of bitcoin to a friend, you can also create on with this website:
https://www.bitaddress.org The website should be used in an offline mode and the computer should be a fresh install that was never connected to the internet.
Which is a far riskier way of doing things.
The complicated part of generating a paper wallet is setting up an airgapped computer with a clean install of a reputable open source Linux distro. Once you've done that, you still need to download, verify, and transfer to this computer the software you are going to use. This is the same for either Bitcoin Core or bitaddress. Then the only difference is whether you load a piece of software or whether you load an HTML file. It really is not that much more complicated to use Bitcoin Core than it is to use bitaddress.
Further, given the huge number of people who have lost coins from websites generating insecure paper wallets (even when offline), and that bitaddresses uses javascript which is a very poor choice when it comes to generating entropy, I would strongly suggest not using any website to generate a paper wallet.
