I would say inferior as it doesn't sound exactly like a 6505. Not that it is an inferior tone, it is a little different a little tighter and personally I quite like it, but for the sake of argument *Does it sound like a 6505 exactly?* then no, so in the eyes of a 6505 supremest it would be inferior.
But overall it has a great tone, the clean channel blows me away also!
Reverb is quite nice also
Here's a clip I made, it blows but you know....
*I copied the settings from Poidaobi's clip*
