Hi Make - I saw that you commented on a geotools page. You should try the geotools user email list (or jump on IRC freenode #geotools if you actually want to grab some help).
Hard question on who is better - our code sometimes dates back to original fortran and made in reference to the open source project "proj". I have met cases where GeoTools is more accurate. bursa-wolf parameters are the numbers that tell you how to go from one coordinate reference system to another (if you have exact values you can do the work in one transformation with better accuracy; if you do not it may take a round trip to lat/long and lose both time and speed, and if it is really bad you just won't be able to do the transform).
