THis is an old story - it's never going away so I might as well jump in. Personal opinion only below. Not trying to get anyone all jacked up.
If you look on Reverb there are thousands of Les Paul's for sale in price ranges from $450,000.00 to $1000, more or less. The top end of these (played by Clapton, Peter Green, etc, etc) are a category unto themselves (PRS himself points out that most people have never even had the opportunity to hear these guitars, much less play one). So discussing these can be fun, but academic only and perhaps pointless.
Regarding the Les Paul's that most of us might one day possibly own (or we could consider the Les Paul's that could be had for the price of a core PRS) - I have heard many of them, through all kinds of amps, in all kinds of genre's. They are what they are and there are quite a few I'd love to have BUT...
I think the 594 sounds better.
I think the 594 is designed / aimed at the classic Les Paul sound and I think it hits it's mark.
I think It might not sound as fabulous as a 58 Burst or any other $100,000 plus Les Pauls' - but it sounds a hell of a lot better than any Les Paul that can be had for under $10,000
