"best" is entirely subjective. One player's going to like polymono over a syn gut, others wont' touch poly type strings (which is most of these strings) with a 10 foot pole.
Need more criteria. If you are accustomed to polyester type strings, these strings vary. I personally like a firm/dead stringbed, but a crisp feel. The Let 'r Rip is dead, but plays quite well in certain frames. The Polymono is a crisper poly, and the SSH/SSS are great poly strings, all around decent, but they'll all lose tension pretty quick. If you dont' break strings often there isn't really a reason to go poly unless you are trying to firm up that string bed or get some added spin POTENTIAL (you're not necessarily goign to get added spin).
