I'm sure everyone has their favorite, so you may get a variety of opinions. This may not be relevant, but years ago I had a '66 Nova with the 350 HP L79 engine. It had Flowmaster 40s on it when I got it. The droning noise and resonance at certain RPMs was so bad I had them replaced with Magnaflows. No more headaches! I can't say the Magnaflows were much quieter, but they were certainly less annoying.
You might find this comparison interesting:
