MultiSite vs WP-Client Login

Hi,

I’m a beginner to WP and MultiSite.

Summary: Pros and cons of Multisite vs WP-Client Franchise Management

I did some research about it and understood that Multisite is great for franchise based clients.
But still, I would like to ask if it wouldn’t be ok to create one single website, and use wp-client or wp-customerarea and split between franchises, so I would have just one users table, split by franchise.
The posts I would also use the franchise to show only posts available for that franchise.
Mainly because 50% of my data would be for all franchises, and the other 50% would be specific.
I saw the WP Broadcast plugin, that would help with posts and pages, but I still think I can split it by franchise.

I already posted this question before, but I can’t find it on the forum/never got one e-mail about it, so I’m creating a new one (sorry if you saw this question before)
