I am pretty happy with the tone of these strings.  I tried the Martin Marquee and hated the tinny tone initially, but then loved the tone after breaking them in or getting used to the higher pitched tones, then hated them again, because they didn't last long.  These have a nice even tone across the board.  They seem to have good tone with a pick and fingerstyle.  I have a rather heavy hand at times so I may be hard on strings.  These have stayed in tune well and still sound pretty good after a couple months of play.  The Marquee only lasted a month.  But they were also lights.  That may have affected the tone and life of those strings with my heavy hand.
