Which is better, a fussy speaker or a versatile one?

Like comparing a Ferrari 296GTB with a Ferrari Purosangue.  One needs special conditions to perform at its best, while the other performs well in any conditions.  Different target market

Fussy speakers usually have issue with even dispersion, time alignment, or lack smooth frequency response. I have found all well made speakers that do the things listed above well are easy to setup. 

A true audiophile would insist on high price and impracticality.  Actually, many of the custom horn systems I really like are sort of practical speakers.  They all sound great in small rooms and are extremely efficient (100+ db/w, typically 8-16 ohm nominal impedance).  The downside is mainly a large size and somewhat high cost (the best drivers are vintage and not cheap).

@larryi I can really see the benefits of horns in these types of scenarios. 

I would prefer a more versatile product. One the works well in my current environment and will accommodate  any changes in the chain.  I also prefer smaller listening rooms.
