I am not sure I addressed this directly.
IMHO, while the technology may be similar, the Vento ceramic tweeter is a step above the Infinity CMMD tweeter.
The CMMD tweeter used in the Infinity Reference R162 is an outstanding tweeter especially considering it is in a speaker with a MSRP of $450/pr. (or <$200 when on sale, as it is now!).

It has extension beyond my experience of what is possible with a soft dome, but no indication of breakup (like the Paradigm Studio20 v.3 had - cymbals had a "bacon frying" sound to them that was subtle, but became apparent when directly A-B'ed against Paradigm Signature S-2 v.2 w/Be tweeter).
The difference between the Infinity CMMD tweeter and the Be tweeter shows up most obviously in the fullness of the harmonics of Orchestral chimes, where the S-2's Be tweeter simply outclasses the Infinity CMMD tweeter.
The Vento variant of ceramic-aluminium tweeter is marginally better than the S-2's Be tweeter, and marginally behind the Focal Solo6Be tweeter, so I would consider it in the same class as the Be tweeters!
