Any difference between those?

You know, just want to know before I install Fubar... I have Titan alrdy

For the most part they serve the same purpose. I also use Titan my self for a couple of years now and have been very happy with it.  Now that TitanPanel has the ability to use Broker plugins the possibilites are enless. Fubar can also use these broker plugins with an optional addon.  So unless you get a response from someone who's use both I think it will just come down to preference.

So it's up to the user in the end...

Good to know. I've been using titan myself too for years and I'm feeling for a change here :)

I like Titan more than Fubar, but since they're both just LDB display addons now, it makes little difference.

I have tried both. In my experience, Titan is a higher quality product and its plug-ins are generally updated more often. However, FuBar has more customizing options as far as functionality and appearance. Because of these differences, at one point I was using both. I suggest trying them both and either choosing the one you like better or using both of them according to what you like best.

Amazingly enough, I get asked this question quite a lot.  My recommendation is pretty much what has already been stated; give them both a try and use the one you feel more comfortable with.  You won't hurt my feelings if you decide to use FuBar.

FuBar, Titan panel and any of the lib data broker displays all do relatively the same thing.  Titan is the original right behind the old info bar from Telus.  Fubar came after using the light ACE frame work.  Now, data brokers are the new kid in town.  FuBar still holds my preference as the mods tend to be updated quickly and it overall tends to be lighter than Titan.  I haven't tried a data broker yet but I do have an addon that allows them to display in Fubar.  The only gripe I ever has was that topscore fu only outputs one item in the crit record list while critline for titan panel spammed all of them.
