I'm not so sure. It all depends on how much direct sound vs reflections you like in your soup, kind of. Most people tend to like a fair bit of reflections, as it makes the sound feel more enveloping. For this reason, near-field speakers often benefit from broader dispersion. And given that the direct sound dominates, one can often get away with a dispersion pattern which is not perfect. On the other hand it's usually important that drivers are not too far away from each other, so they integrate on a short distance.
For the far-field, however, one will in any case get more reflections. Hence it becomes more important with even dispersion. And when listening far away, it may sound good with narrower dispersion, as this will give you more direct sound relative to reflections. It's also less of a problem with drivers placed apart.
A personal example: I purchased the D&D 8Cs speakers, and expected to really love them. To my great surprise, however, I found that I preferred my old AVI DM10 actives, which are inferior on paper on most accounts. Why? After much experimentation I found out that it was about my listening distance. I mainly listen in the nearfield, and given that the 8Cs have a narrower dispersion than the AVIs, they became too "dry" for my taste. In the mid/farfield, however, it was no contest at all. The 8Cs had a homerun and then some. Their stereo image was much superior when listening at a distance, because their dispersion pattern is more even and narrow.
Off-topic, but the above statement is not factually correct. We have 60 years of research and statistics which quite conclusively say otherwise.
