Which sounds better 2 way or 3 way speaker design

I prefer 2 way stand-mounts with specific OE stands that are designed for use with the specific 2 way transducer. 

I have 2.5 way floor standers and they sound nice bust not as clear, detailed or have the depth or breadth of my 2 ways. 

Now there are many variables that play into this also, room size, room treatments and so forth. 

I have no knowledge of the three speakers in question.

Whether a 2 or 3 (or 2.5 or other) way is best is dependent on the selected components, construction, and it’s implementation. There are fine speakers made in many "ways" and I don’t think that the actual number of drivers is the important factor in deciding which to choose.

In general, I would think that a floor standing speaker would offer more cabinet volume and this would typically allow for a deeper, more generous bass. But of course there are exceptions to everything.

A 4 way and don't look back! 

I've upgraded through the Usher line over the years. Started with BE-718s then Mini One Diamond, then Mini Two Diamond. I prefer the fuller mid bass and the richer sound of a larger output speaker design.

Incorrect question, All depend of design, drivers, crossovers etc
