Are you referring to the two acoustic models made by Paul Reed Smith Guitars?
Tonare: http://www.prsguitars.com/tonaregrand/
Angelus: http://www.prsguitars.com/seangelus/
If so, you wouldn't go wrong with either one. PRS makes very high quality guitars, and if you personally like the sound and feel of them, you've got a winner. I played one of their electrics a month or two ago, and was very impressed with the quality of workmanship, and the gorgeous finish. Their signature bird inlays on the neck are also very cool. After watching the demo vids for both, I'd likely choose the +/- $1000 Angelus over the $5000+ Tonare. The Angelus sounds great (lots of rich voice & detail), and I can't hear $4000 difference between the two.
