Try one of everything until you find the best ones for your instrument. Whatever everyone else recommends as their personal favourite are unlucky to be the best for yours.

Having said that, bog-standard D'Addario strings seem to be very tonally "flat" - uninspiring and uninteresting, but a good baseline. So use the basic D'Addarios to get the right weight of string (9, 10, 11 or the monster 15s? - note that string sets are always quoted by the size of the top string). After that, you'll know where your instrument needs extra help - more bassy strings, or more treble, or richer overtones, or whatever.
