after receiving the config you will get access to the system
True.
As soon as you have access to a device, the 'cert' method opens also the remote LAN ....
Let's say I presume that tools like OpenVPN-client are not (never) installed on devices that have shared users.

and users can leave it on a flash drive or somewhere else
Yep.
And they have the VPN login and password - just several characters - in their heads, which can be 'copied' also very easy to another head.

What looks more secure to you ?? ;)
The important word here is "looks". Which is close to 'mystification' or security by obscurity.
Because using certs or passwords to ID yourself is the same thing.
The latter is easier, after a couple of hundreds of VPN logins ..... as we all do lately.
