I agree with all those who said the strings are a presonal thing and that they depend upon the guitar. For a long time I believed our local guitar sales guy that D'Addario phospher/bronze lights strings were the best for my guitar (Maton BG808L--a 00 sized guitar) because that is what the factory supplied them with. A short time ago I put on some Pearce 80/20 bronze lights. I played with them for a day and by the next day my guitar sounded better than it ever did before! I can hear it myself and so can others. I am going to experiment a bit now to decide if it was change to 80/20 or if it was specifically the Pearce strings that made the difference. When I tell this to people they say, nah! 80/20's sound dull compared to phospher/bronze.

With my nylon-stringed guitar I like Hannabach blue, which are fairly high tension strings. I think this is, in part, because I play a steel string guitar and tend to have a heavy touch. A friend of mine who has a far better and more resonant classical guitar, and who only plays classical, hates the high tension. He can't make a good clean bar chord with them for one thing. But on his guitar, normal strings sound louder than the high tension ones on mine because of the better instrument. I dislike medium strings for that reason. I just can't make barre chords sound clean with them.

I haven't tested this completely, but I think the Pearce strings hold up longer under retuning--that is going from one open tuning to another.
