They typical import option has said "recommended" for over 5 years now, however this is not something that any support technicians would ever recommend doing, they would always suggest the custom import as the risk of missing data during a typical import is very high. It is a misleading message and really should be changed.
On the subject of the typical import, if you choose that option it will give a message saying "All fields are compatible". Again this is a very misleading message as it does not tell you if any fields have failed to match. Essentially it means that all fields it has matched are compatible, but this is far from obvious. It should definitely tell you if any fields have failed to match so that you can then go through a custom import instead.
