vB 5 or XenForo?
 

This post is meant for getting ideas only.

I currently have vB 4.2.3 for a client's site I manage. The site is not mobile friendly at the moment. So there are 3 options we are considering now.

1. Make 4.2.3 mobile friendly somehow (maybe new theme and stuff).
2. Upgrade to vB 5 to make it mobile friendly and a revamped look.
3. Move to XenFor to make it mobile friendly and a revamped look.

What do you guys would suggest?

If mobile friendliness is a priority then vBulletin 5 should satisfy the client. If the current forum of the client uses a lot of plugins that are a must-have then it might be a better option to look for mobile friendly themes.

I don't have any experience with XenForo and I doubt you're getting much support for XenForo on a vBulletin modifications forum.

Thanks for your input!
Mobile friendliness and a beautiful looking forum is what we're after. After checking out a few XF forums, XF qualifies for both of these for us. But I haven't really come across vB 5 forums to see how different it is from vB 4. Is there a demo available for vB 5 or maybe name a few sites running vB 5?

The official vBulletin forum runs on vBulletin 5: http://www.vbulletin.com/forum/

Thanks!
What are the plugins like for vB 5? I've been able to find a plugin for nearly everything I wanted to do. For example, MarkFL's Additional Thread Tools is a very useful plugin for me (Super sticky option) and this particular plugin doesn't support vB 5.

I will not comment on third party software in a vB forum, but I would not touch vB5 with gloves and a 20 ft pole.

VB5 is much better and stable now

I mostly develop vB5 mods. One of the advantages of vB5 plugin system over vB4 is a Module or Widget plugin can be created and added in Sitebuilder in the frontend where Admins can drag and drop that module onto any page. Sitebuilder is a new feature in vB5 which older versions don't have.

This is thing I did for our marketing forum and it worked really great.
I would recommend using this way.

In other words, it depends on you, if you feel XF or vB is better then you can go with your choice.

The support is same as vB but if using XF, you need to pay extra for yearly fee for updates and addons for Xenforo are pretty expensive while free addons on Xenforo are not really effective to use.

Do you have a large number of mobile users, who absolutely cannot use the site ?

(I'm wondering why you are so worried about "mobile friendlyness" that you think you need to upgrade).

Dont do it just to buy into hype.
