your best bet is to scrap all the exhaust piping and manifolds and just have the heads venting directly in to the engine bay. But for real, there is no 'best muffler' because everyone's gonna have a different opinion based upon their experiences and setup.
What you said is the cold hard truth. In ignorance, I bought a set of Flowmaster 40's, and they sound great, and would be a great choice for a strictly track car. Otherwise, welcome to the drone highway.
Mufflers, ideally, should be selected based on performance, and sound. A basic understanding of muffler types should help guide the user. A reflective style, like the Flowmaster 40, is going to drone, no matter who manufactures it; yet, they still sound great when they aren't in drone mode.
A restrictive style is what comes stock from the factory: no sound to speak of, and, as the style suggests, restrictive flow and performance.
Finally, a sound absorbing type of muffler, i.e., glass pack/bullet/magnaflow performance design, are the least restrictive, while still delivering the sound of the V8 engine.
