Wilsons are the best speakers in the world

When at their best, i think the newest Wilsons are top five or six. Along with YG Acoustics,  Magico, Marten, Kharma, Vivid.

At the very least you omitted Lansche, Focal Grand Utopia and MBL.

This comment is correct: there is NO best speaker. 

It is about what YOU prefer most. And don't forget component matching.

I happen to like Wilson Sabrina's very much. I also like MBL very much as well. 

Everyone has a important  set of parameters they find important, 
And please remember unless same power cords, system cables 
Amp,preamp, source, even room  even the best gear I gave heard sound 
Not so good at show settings even Wilson's, Magico  and many others 
Some like cone speakers, ststs,planets, omni directional  open baffle  
And many other type . This topic is not winnable.
There are a Lot of fantastic speakers made . I heard the mid price ,for Wilson 
Alexx a excellent Loudspeaker on every parameter. The marten Coltraine-3 is also 
Great for $ 120k. Maybe next year, it would have too be one Exceptional year.
Myself in the $15k and under speaker New series Martin logan  which I feel so many things well.  When buying a new speaker your audio cables may or may not 
Need to be tweaked depending on their perspective to your speakers.
My point any new product in a Audio system does not guarantee system synergy.

Most people I have met in this hobby have no idea of what they are listening to, no idea of what real music sounds like, judge audio based on reviews and what others say, and think that a speaker that can play loud with powerful juke-box bass is great.  And everyone is entitled to their own opinion of what they choose to buy with their own money. That's the way it is, IMO.
