Which Tweeter preferred- dome natural material, Beryllium/Metal or Planar Ribbon? Why?

Silk is the best!  No wait, Beryllium is the best… Except for ribbons.  No wait, Maggie's are the best!  
 

I think its safe to say that there are fine examples of each.

This question is like which flavor of ice cream is best?  

Aurum Cantus true ribbons and AMT. I love um. I like two horn loaded planar designs to. They were over 25khz

There are a lot of soft domes and rings I like to. They just don't have the range.

There is not a single hard dome I like, diamond, Beryllium, iron, magnesium, SS or tactile. YUK!

Mid range that different. There is a couple tactile domes I like 1 1/4" - 2" or so.

I think dispersion plays a bigger part. A wave guide or wide baffle vs narrow baffle changes things a lot. Motor and back waves matter a lot too. 
 

For a direct answer I find silk domes are kind of dull in general (some exception in there) but in general I like BE tweeters done right. 
 

the standout performer for me is magnepan’s ribbon in the larger models but the lack of dynamics in the lower mids and bass does not do it for me as a whole. 

2nd Be tweeters done right. The few ribbons I’ve heard were awesome but have no impact which is weird to say for a tweeter. Dynaudio soft dome ain’t too bad also.

Eric. Name them please. Really curious.
