Dome material/coating is not the key here. BlieSMa has unique construction. Be in general makes dome stiffer and thus reduces resonances above audible range and thus also gives lower distortion figures.

2.5mm of linear excursion! It's a real deal. Although the breakup takes place above 20Khz and is not audible, but I can't take my eyes off the SB TW29BN with no breakup at all! This is really something. It goes all the way up to 40Khz with flat response.

Where it wins out over the other options in general is the ability to cross low/ or use lower slope filters due to it's high xmax. And it's ability to play at really high spls without loosing it's composure.
Clearly one needs to make a choice of whats the best compromise there as those works against eachother.
Look at the distortion figures at hifi compass etc down low and compare it to the other options.
It has the higest rated sensitivity of the available non wg choices.
And it has a lighter diaphgram then them.
With a rated field strength that is unusually high, and lower inductance than the competition, which are both signs og a very good motor design.
The Impedance is nice, clean and very linear through its range.
Just be aware that with the fairly small back chamber and no ferrofluid etc, the FS is fairly high. If you want to take advantage of the ability to cross it low.
And you are using passive XO's, it will require a impedance correction to sound it's best in my experience.
It is a larger dome then the competitors so it's off axis dispersion is of course slightly worse in some cases, which is the tradeoff for a 34 mm dome tweeter.(The T34A aluminum diapgram with it's shape does as well here as most 1" domes though)
The diaphgram is also using a very minimal surround in comparsion to the competition.
As for subjective sound quality vs other BE dome tweeters i can't help as i only have the T34 B. And it would anyways be a personal opinion.

Personal opinions aren't de facto useless. If not comprehensive grounds for running out and buying them, at least it's a data point.
The value of a personal opinion really depends on the person's reason for formulating the opinion. I for one would be interested in what you have to say.
eg. If you do like them then what about them do you like? In relation to previous types you've used, what makes them different or what makes them the same? etc

2.2T and 34mm .26g longer stroke with very narrow surround Beryllium, Im no expert with measurements but how could this not be amazing if built very well, possibly with the 3” beryllium mid M74B on each side and while were fantasizing a bunch of the annular 168 Accutons of course with 6” or whatever BE diaphragms and whatever adjustments necessary, and the 18” Oberton. oh, and a RAAL Tweeter in the middle of it all, Crossover designed built by Duelund himself because that has to be a Brilliant crossover. Just turn all of those drivers into a perfectly made Line source with a gigantic box behind it for the 18”. This speaker would ideally weigh over 800 lbs. and is basically a Joke to me but if the right team built it i’d like to hear it.
