MyBB forever, since it's so simple!

I prefer MyBB.
It's more simple, and I'm used to it.

MyBB, easier and free ofc!

MyBB easily. I feel like MyBB has more customization options than vBulletin does.

MyBB, more themes available and free of cost.

I strongly encourage you to use MyBB. MyBB it's free ..

MyBB is decent for a free software. vBulletin needs a lot of securing, plus a license is costly.

Xenforo all the way!

I really like MyBB, probably the best forum software so far.

MyBB easily. I mean, it's free and does the job which vBulletin does. If you're making a simple community why spend so much on a license. If you're a business then I mean it's up to you. Plus, vBulletin requires security knowledge.
