Drupal Commons vs Buddypress vs Ellg

This is an old thread, but maybe someone can still find this useful.

1. Groups (ability to disable users from making there own groups or making private groups).
Yes
2. Group images (this image should appear everywhere within a group)
Yes. But I'm not sure if it appears everywhere. But you can build your own theme or tweak the existing settings.
3. A members avatar thumbnail widget in sidebar of a group
Yes
4. Friends online widget (avatar)
There is a who is online widget. But it is global. I presume making one just for group members shouldn't be that hard.
5. Admin can disable members from deleting there own content
Yes
6. Members can edit there content but admin can set a time to lock content, after that, contents cannot be deleted
This could be done using rules and workflow or workbench moderation, but it is not an out of the box functionality
7. Groups can have an advanced forum. (merge threads, split, make sticky and super sticky threads, reply to posts, attach, advanced signatures, bbcode and image code)
There is no merge threads or split. There is make sticky but not super sticky. Of course you can reply to posts, attach, have signatures, not sure what you mean by advanced. You can add a bbcode module and attach images in the editor using special image tags (probably the best way is using the media module, but there are many options)
8. Can assign Group admins and mods
Yes
9. Events, side wide and group wide
Yes
10. Group polls and site wide polls
Yes
11. Group blogs
Yes
12. Group Wiki
Yes
13. User state updates
I'm not sure if there is an out of the box functionality for this, but you could build it yourself.
14. Members photo albums
Same, not out of the box.
15. Group event calendar
Yes
16. Can Promote users
Yes
17. Users cannot delete there accounts
Yes
18. Ease of use (updating and plug in installing etc)
Yes, but drupal does have a learning curve.
19. An elegant look
That depends on taste. I like the default drupal commons theme, but I'm not sure it is elegant. Of course you can change it.
20. Extended User Profiles and ability to add custom profile fields
You can add your own fields.
21. Group specific User State Updates
You have user specific posts.
22. Does softaculous or fantastico provide quick installations for drupal commons or is it already planned?
I don't think so. And I don't think it is planned. Only for drupal, but you can't install drupal and later add commons.
23. Can admin set a limit for how many user updates a user can submit a day?
No
24. featured groups, blogs members, posts forums threads etc
Yes
25. Sub groups (a must)
There is og_subgroups (https://www.drupal.org/project/og_subgroups). Drupal commons uses og for the groups functionality. But you would have to integrate og_subgroups yourself.
26. Ability to disable notifications
I'm not sure which notification system they are using. But I think the answer is yes.
27. Ease to navigate to group content modules like forums blogs etc
I think so.
28. And things I cant remember right now
