Research has indicated that people prefer speakers with wider dispersion on average. Now, we don't really know if that's a strong majority or what, nor how different speaker configurations and rooms impact it, if at all. And it's certainly not universally true.
But it stands to reason that if you're in the wider dispersion camp, then yes, you like echo, because if you use a speaker like the Revel Salon 2 in the farfield, you're absolutely going to hear a *lot* more reflections than a main monitor with extremely narrow dispersion like the S360A(which looks like +/- 45 degrees according to spec).
In the relatively-recent AVSForum blind test of the Salon 2 vs
JBL M2, another very narrow dispersion main monitor, the Salon came out on top. Whether that's the main reason or not, of course, is up for debate. But it does seem to be quite common that people prefer the level of reflections that you see in the yellow-colored regions on the Genelec chart.
So whether or not going up to main monitors is actually better for you or not really depends on preference more than listening distance alone, I would say.
