I run a big board and am still on vb3. I speak to a lot of other big board owners. Most "would not touch vb4 with a ten feet pole". (exact quote)
vb4 offers nothing of interest that makes it worth while to migrate to that. It does have:
- 800 bugs. Even though there were thousands more, 800 bugs is still an insane amount.
- an aborted rewrite. Meaning spaghetti code and low coding quality.
- looks just as outdated as vb3. It can not exactly compete with XF or IPB. lol.
- the vbCMS suicide issue
- various unwanted addons no one asked for. (which can be disabled)
So with these handicaps, what does it offer to make it worthwhile to upgrade?
Currently nothing that I see within vbulletin.
What is worth considering is certain addons only available for vb4.
