Trevor is correct. Strings are a personal choice. I have used many different strings over the years.
I now prefer D'Addario, either the composite EXP45 normal tension or the EJ45 Pro-Arte normal tension. Many may speak up for higher tension strings...for a louder, stronger tone.
I prefer the sweeter, normal tension...maybe it's that BossaNova sound I love. My guitar is (solid) rosewood with cedar top and mahogany neck with rosewood fingerboard, the instrument will affect how the strings sound.
Short answer...try lots of strings, tune carefully (good chromatic tuner) and listen...then pick the ones you stick with.
