Paradigm Persona B vs 3F vs other competitors - any experience?

Hello all, 

I am Robert, 50 and would like to ask for any experience of the forum members concerning Paradigm Persona speakers. 
Was wondering if anybody has heard both, the „3F“ and the „B“ in comparison in a room 350-400 sqft?

I had lend the 3F and to me they were simply amazing. Unfortunately my wife does not like floorstanding speakers in the living room, that is why I was thinking about getting the Persona B. Unfortunately no dealer has the Persona B for a demo.

How do they compare sonically to the 3F - non fatiguing, richness, voices, foundation, bass etc.?

Does anybody recommend stand mount speakers from other brands performing similar to the Paradigm Persona  B, especially lovely vocals, great resolution, still rich sounding and non fatigueing?

Thank you all for feedback.

Best
Robert
