vBulletin 3.5 vs. IPB 2.1

[CrimsonBat]

I am very interested in both vBulletin and Invision Power Board. However, I can only choose one and thus require your opinions on these topics so I can see which one suits my needs better. I understand that this is a vBulletin forum so the answers are biased, however, this is the opportunity for me to know why vBulletin is better.

1- Skinning
In terms of Skinning, which one do you feel has the best skinnablility? Is it easier to skin with IPB or vBulletin? Why? Which is more versatile to edit?

2- Management
I personally tried out the demos of IPB 2.1 Admin Panel and the vBulletin's demo. However, I noticed that IPB's seems to be much more professional than vBulletin and had a much cleaner feel. vBulletin's Admin Control Panel seemed to be a bit sour for my taste. Is there a way to change the style of the skin in vBulletin?

3- Modding
Both IPB 2.1 and vBulletin seem to have pretty good mods. Which one has more? Is it easier to mod with IPB or vBulletin?

4- Features
Both software are chock filled with features, so many that some people call a few of them "bloatware". But which one has the most features? Are the features in vBulletin or IPB what you consider to be "bloatware"? Are there features in vBulletin that IPB doesnt have? Are there features in IPB that vBulletin doesn't have?

5- Ease of Use
In terms of the criteria from the 1st 4 subjects, please tell me what you feel is the ease of use. With many features in both vBulletin and IPB, there comes the fact of the comfortable setting of getting something done. Which has the upside in ease of use?
