pros and cons: beryllium vs ribbon tweeters in sound and emotions terms


After a lot of searching and reading on web, there are some forums and documents where you can learn and understand the differences between this two, and basically you can conclude the ribbon are better; but in terms of sound or musicality (basically nothing on web), how they differ? which one is more involving, natural, emotional if you can say? so you can spend hours of listening AND having a realistic 3D sound experience at the same time without adding any character?
Would appreciate comments from people that have actually heard both and some brands/ models recommendations from each type.
Thanks for the comments

The specially doped berrylium tweeter which is paired with a rear facing ribbons ambience tweeter in the new Von Schweikert VR55 yields the best treble that I have ever heard - fast, subtle, detailed, dynamic and absolutely no peakiness, overemphasis, edginess or harshness.
I'm surprised no one has commented about plasma tweeters such as those in Lansche speakers. I've heard all types of tweeters including Be tweeters  in my current Rockport speakers. IMO, the Corona plasma tweeter is the smoothest and distortion free tweeter I've ever heard even though it doesn't fare well at very high volume levels.
There is my point, yes i guess the von schweikert vr 55 is a great speaker but you found ribbon tweeters in the highest lines, the same happens in other brands, monitor audio, nola, legacy, dali, and i think there are well stablished brands that dont used them because of reputation, i mean there highest lines with 5 ceros prices, has always used domes, to late to change the path, 
Hello...
Sorry,  not a contribution to the specific model but a question....

Looks like I might be able to pick up a pair of VR-5's locally for approximately $1,000.  I had a pair of VR-4's last year.   The ones I'm considering are in VERY good shape - well worth it if I can get for this price?

Suggestions/comments?   Thanks!
