Is phpBB or WordPress better for a multi-user site with login?

[narutodude000]

I have both a WordPress blog and a phpBB forum as part of my website. I want to use one of them as the login for my website, which one should I use?

I heard WordPress is more secure and stable, but phpBB has features such as Private Messaging, Friends, etc.

So which one do you think is better?

might help to know what you want the users to be able to do once logged in.

do you want them to be able to publish content on the main website, or just interact in the forum, perhaps a combination of both?

there are projects out there that look to combine user databases between phpBB and wordpress but depending on your use (again im not sure what kinds of functions you want the users to be able to do) i in-vision something like drupal/phpBB might be a better fit. but then again since i dont really know what you are trying to do maybe not.

I'm currently using phpBB for everything WordPress. For example, when a user posts something in WordPress, $user_id has to exist (to show he is logged in). I changed $user_id to $phpbb->data['user_'id']. This way, the users have to be logged into phpBB to post in WordPress.

I can also do it the other way around if phpBB is better.
