Although I haven't owned Magnepans (I own and sell Sound Labs), I've heard them on enough occasions that I have a pretty good idea of their characteristics. Their radiating pattern gives a different tonal characteristic and feel, the former being somewhat variable depending upon listening position. When pushed hard, Magnepans can probably reach higher SPLs than Sound Labs, although one should consider what your listening satisfaction levels are at various SPLs. Keep in mind that your ears tend to protect themselves from loud sounds, that as SPL increases you may likely hear less detail. A loudspeaker which excels at low to medium volumes in terms of detail doesn't necessarily need to be played loud to be satisfying, although having the headroom for producing momentary loud sounds can make things more realistic. Conversely, a speaker that needs to be played at medium to high SPLs to sound more satisfying probably lacks some detail.
As for radiating pattern, the faceted curve of Sound Labs enables them to deliver a wider listening sweet spot, with more accurate tonal balance in the room, as pointed out. A speaker with a flat planar diaphragm may reach higher perceptible SPLs since the sound is coming more directly at you instead of being radiated in a more radial pattern that a line source produces, which my seem to have more impact. Magnepans do seem to exhibit a bit more 'thwack' of a bass drum, but the overall presentation including ambient information is quite different. Tympani, string basses, and pianos all produce lots of bass in all different directions. Ask yourself the next time you play a record or CD with those instruments, am I experiencing the sound of the instruments in the performance venue? The human voice also reveals a great deal. It all has to do with getting the reverberant field right.
