its not about the money , or what you can buy , Both software's have the capability to achieve what you need or want , its just what you prefer .... Now as far as either IPB3 or vB 4 , as Marco stated , you cant compare an unreleased software to a current one .. but if you need to start , then you know where to go ...
v4 Seems to be far still.. at least in my perspective , is it worth the wait? , you tell us .. do you like current vBulletin? then expect greater functionality with vB4...
Its too early to decide however which to go for :-) , if you want the best , then yes wait and compare to your likes.
