One reason for advising a user install is the vista/w7 virtual store
abomination, which makes a user think that he has installed
something under program files, while he has only installed it in a
fake program files directory; same for HKLM/HKCU registry entries.
You run into this when you run the installer with admin privileges
and then TeX Live manager without.  This can be avoided by not using
admin privileges at all, especially since most Windows machines are
single-user in practice.

The difference between a user and an admin install lies in
system integration (search path, file associations, menu shortcuts,
uninstaller registry entry): are either for the current user or for
all users. These features are non-essential, optional and
Windows-only. Other users can still use TL from the command-line by
adjusting the searchpath or by starting from the system tray thingy

There is no difference in the directory layout.

If you turn off system integration in install-tl-advanced then there
is no way your TL installation could interfere with your miktex
installation, and you will be able to answer a lot of questions
