2.5 or 3 way; why one over the other?

Thanks for the link but the info there doesn't really speak to my question.  I understand that a better quality 2 way system may well sound better than a lesser quality 3 way.  I was asking about systems from the same manufacturer, in the same product line series, presumably using the same quality drivers, crossovers and other components, and having a modest difference in price.  What, typically are the differences that would tend to cause you to choose a 2 or 2.5 over a 3 way, or visa versa?

Width and sensitivity are two attributes that come to mind.

2.5 ways are often narrower, deeper than a 2 -way, but also have more output per volt.

In some ways I think they are the ideal apartment dweller’s speaker.

The extra woofer helps overcome the "baffle step compensation" issue, but they do tend to have a little lower impedance as well. 

Unless you really need to go very low and play your music very loud, large scale music at near concert level, great 2 way floorstanders that do 30hz well is all that's needed for a medium size room. One tweeter and 8" woofer. And great source and electronics. And wall current and cables. Speakers should be as simple as possible in terms of parts and wires. Building cabinets and tuning speakers is a different matter.
Can't answer your question, though, your ears should tell you which ones to get.

With a 2.5 speaker the woofer and mid range are the same size. With a three way speaker the woofer and mid range are a different size. They both have two crossovers. I have owned Spendor 2.5 way speakers and they were outstanding. From what I gather that is the difference between the two types!
