I carry 2 brands with Be tweeters (Revel and Focal), and no they dont offer much if any difference over the Esotar tweeter, which is a proprietary Dynaudio design (I also carry).
I think as you mentioned it more or less has to do with implementation which takes into consideration the cabinet design, crossover network, and the midrange/woofer designs. This will affect the overall sonic presentation more than just a fancy driver material alone.
I think Dynaudio is the best soft-dome tweeter currently on the market, while Revel and Focal probably make the best metal tweeters right now. Again Im saying not 1 solution is better or worse, just different. You would need to let your own ears decide this one.
