I have several questions regarding apt-get vs. dpkg.
- Do they install to the same place?
- Is info from these tools 1 to 1 with each other?
- Is there any difference in the commands utility?

Method 1
apt-get makes use of dpkg to do the actual package installations. So in a sense they’re “installing” to the same place.
I would always use apt-get to do any package management since this is the tool that understands how to source packages from remote repositories and provides capabilities for searching the meta data related to packages either locally or remotely.
That being said there are times where you’ll have to make use of dpkg to perform queries against the system to find out information about the packages that are installed.
The major reason to use apt tools though is for the dependency management. The apt tools understand that in order to install a given package, other packages may need to be installed too, and apt can download these and install them, whereas dpkg does not.
