Werbean,
I haven't heard of it before, but one way to compare is simply to go though the respective forums and determine what types of questions people are asking. Also download the tutorials for each and that'll also give you some important information.
After a very preliminary look-see, it appears to me that the Bunkspeed users are imaging products; buildings, not so much. Also lots of comments about installation, and the software seems to still be in beta. Exciting stuff for a student, but beyond scary for anyone trying to get paid.
Assuming it is great software, the true cost of software is never the purchase price ($995 base), it is the learning curve, plus the ability to get help during crunch time. IE how good are the forums and tutorials.
Let us know how it goes.
