I think you misunderstand: with L2TP/IPsec you can use both PSKs
and certificates. You do not have to use 'plain' IPsec with

Nate Carlson has a separate page about L2TP/IPsec with certs:

This is a configuration for plain IPsec. If you use L2TP/IPsec
you don't have to install and configure the ipsec.exe utility.
That is the whole point of L2TP/IPsec.

If you don't mind using Marcus Müller's ipsec.exe utility this has
the advantage that you do not have to use an L2TP server.
