The preferred way to install software should always be to use the package manager provided by the distribution (apt on Ubuntu and Debian based ones).
If the software isn't in the official repository, use a PPA (Personal Package Archive). Preferably an official one. They are kept up to date and provide updates using the package manager.
Only if these two options fail you should use the .deb, and be aware of the implications.
You're not exactly wrong, but some Debian packages (including Google Chrome and Visual Studio Code) provided by software vendors automatically add their own software repositories to system and so are automatically updated using the same package manager.
