Most MOTL and BOTL arrangers have inferior DAC's to their TOTL counterparts, and also compress their sample ROM harder, and use shorter loops, fewer multisamples, etc., resulting in the exact same patch (ostensibly) sounding thinner, brittler, and less satisfying...
But, let's face it. If they WERE identical in sound, who on earth would buy the TOTL?
