Plus, I have enough room on my phone, so it's not like I can't afford to have two apps, but it is visually nicer to me with less app.
It honestly depends on how SE coded their side of the "check". With the open source Google system, the code you see on your phone could expire but SE can make their system still accept that code for 30 seconds or even 60 seconds after it expired. There is no telling what they set this to though. Last time I added this system to some of the systems at my job, Google recommended a 30 second leeway.

IMO I like the new way because I can have my code on more than once device AND also backup the system. I use Authenticator Pro on my Android devices. It's 100% free, open source and doesn't have any code which lets it connect to the internet in it. This is why the app can't do auto-backups to cloud services.
