Enigma - I chose my 408 Brazzy over a Stripped 58 during the GC 49th anniversary sales last year. They are indeed very different animals, and I wish I could have gotten both.
The 58 was probably the best straight-ahead rock-n-roll guitar for my ears that I have heard to-date. The 57/08s sounded amazing, and I think the two-piece bridge does alot, too, as I tried out a brand new SC245 they had just gotten in, and the Stripper sounded better to my ears.
I ultimately chose the 408 Brazzy because the neck felt so damn good, and it was a sick deal (I had never thought I would be in a position to own a PRS with a solid BRW neck). Of course it sounds amazing as well. The 408s, if you have never tried them, are stellar - lots of different tones, and not a bad one in the lot. You will find alot of love for them out here, deservedly so. Playing with all of the different combinations and the tone/volume knobs never gets old (although it ain't no Alembic)...
I must say that I do favor brighter guitars, and as 408s go, I do narrowly prefer my Siggy and Paul's Guitar over the 408 Brazzy because of the low-mid emphasis. I end up running the neck in single-coil almost exclusively on the Brazzy because the neck full humbucker with gain can get a little wooly on my Boogie.
Hope that helps.
