Best forum software/script Mybb, PHPBB or SMF?

Hello, members!

I'm not sure if this has been posted anywhere before, but I wanted to know your opinions regarding two things concerning forum scripts.

1. Do you go for open source (phpbb,mybb...etc) or licensed (vbulletin, IPB...etc) and why?

2. Which is the best open-source forum software in your opinion? Let me know your thoughts

My thoughts: For vbulletin and IPB, I think they are over-priced comparing to their open source competitors. In regards to IPB and Vbulletin, I heard that IPB's security is more powerful and it's admin panels are much easier to deal with than vb and is more user-friendly. On the other hand, many people told me that vbulletin is overall better as it's very rich in features and mods make it very extensible.

For open-source, I tried SMF, phpbb and Mybb and LOVED working with Mybb. I felt it really is the closest to vbulletin in features and people say it's pretty secure. Well, what do you think?

Thanks for sharing!

 

IMO, MyBB is the best just because I like how it looks and feels and because I managed to get it working as a multiuser forum hosting, as you can see if you check the forum link in my signature .
SMF will probably be everyone's favorite when version 2 becomes stable for the resamblance with the paid big ones ;
PhpBB3 is not bad at all IMO, however it sometimes is too slow, it doesn't give you the simple look and feel, I find upgrading degrading so to speak, maybe I'm too hursh on a good product but it's just my personal oppinion.
