I purchased North 3DL sails for my Sweden 38 and took delivery this year. While the cost of the sails were about 220% the cost of Dacron I felt it was worth it since I race. I went with Marathon 3DL (Vectran) for the genoa and full racing 3DL (full batten, Kevlar) for the main. Very happy with sails - only downside is weight since I had taffata put on both sides. My choice in order of sail makers were North (3DL), Quantum (Fusion M), UK (tape drive).
If you are serious about racing I suggest you by the "best" sails you can aford that also meets your other requirements (durability, furling, UV protection etc).
