Hi. I have alot of experience with SMILE and Hugin. I recommend that you download SMILE and at least take a look at it before you spend money on Hugin or Netica. SMILE is a nice package if you want to operate in the space of DAGs (ie, Bayesian networks). If you want perform operations on the joint-tree then Hugin is better than SMILE. I'm not sure how Netica fits in. Also I like the documentation of SMILE alot better than Hugin, although Hugin customer support (and SMILE's) are very quick to respond to emails about their products.
In terms of optimizations, I have not noticed a difference in the two packages, but I haven't done an explicit comparison. If you are using Windows, SMILE's GUI is much much nicer than Hugin's (which IMHO is very frustrating). I realize that you don't care much about the GUI, but for inspection of you networks it will come in handy. Smile can be downloaded for free at: http://www.sis.pitt.edu/~genie/ I think they are planning a new release in a few weeks. Also, Intel is planning the release of an open-source library for operating on probabilistic networks. As far as I know, it is going to be released around the time of the NIPS conference. It obviously has the advantage of being open-source, and (again if you use Intel architecture) it is supposedly will be optimized for Intel architecture.
