WordPress
If you are not an IT person, then given that:
- many people for social sciences learn and use it
- it is easy
- it has many plugins and themes
- it is very popular
- many blogs, forums, lessons help to learn
- it is the USA way of thinking
it is good for all
Also you can write code, this is for IT persons
Joomla
This is more advanced, and
- This is for more heavy projects
- With less plugins and themes.
- More difficult
- It is the English way of thinking
- Less popular
It is good for more advanced users
Drupal
- This can be used for small or bigger sites
- it is most secure
- it needs a lot of time to learn
- It is more expensive in time and resources
- It can be used for very big projects
It is for most advanced users.
For multisite solutions with site generators are not bad, but you must have backup of your data. These solutions are easier because you pay and other work for you, you earn time but you pay, you do not need to learn a lot, others work for you..
If the central serves stops to work and no backup or even with backup, how you are going to work, are you going to be able to migrate your data to another platform ?
For me the best use WP, Joomla, Drupal, or even Typo and more, where the data is yours AND the platform is open source, In This case you are the BOSS of data and you ARE using a FREE platform.
