All speaker designs have pros and cons. If panels had no negatives, so to speak, then that type of speaker will be in demand and the market will dump the other designs to sell what everybody wants to buy.
The choice usually falls to what you are looking for in sound rather than which is the best design or carries the most impressive innovation.
What you may find "annoying" others can overlook, and vice versa. If you have no problem with bass extension then you can look to mini monitors for imaging, e.g., or panels for the large sounding board with the wide sweet spot. But others place a premium on low end response and find that boxes work better for their needs. You simply choose your compromise.
