What is “this”? 
Some folk prefer the Bose “sound” whilst others prefer that of Sonos. Which do you prefer - it’s your money and your ears. 

Also depends on which Sonos and which Bose you are comparing.

Given your question is highly subjective as it depends upon which speakers are being compared and your (ear) preference…yet you think you might get an answer saying Sonos doesn’t sound as good as Bose? 

There is a large fraction of the lay public that believes BOSE sounds best — even if they’ve never listened to BOSE. When asking the above question all these people want is a confirmation that BOSE is “best”. If you disagree, they’ll seek confirmation elsewhere.
