Supratak v. Jadis and/or BAT

Has anybody compared the Supratek to either the BAT or the Jadis? Comparison at any level of each brand is fine, but would be most interested in comparisons of the Supratek Cab or Sauv against the BAT current versions of 31/51 or Jadis JPS2 or JPL.

Just thought I'd bump this thread. Anybody? What about a comparison of the BAT and Jadis mentioned above if no supratek comparisons.
