I understand that this is an important decision to make during a WPMU install since you can't change it later. But what difference does it make (which is better)?
I'm using pSek for hosting and as far as I know they can set up wildcard DNS records, so in my case both options (sub-domain and sub-directory) are both available.
Can anyone shed some light on this?
I've done a forum search but can't find much info. This is all I've found:
"I personally prefer using domain name installations rather than sub directory. You will see people with different opinions including that sub domains when not mapped still appear as a separate site in google where as a sub directory installs appear as part of the main site." https://premium.wpmudev.org/forums/topic/adding-domains-to-wp-multisite#post-160773
