A friend of mine has Whirlwind sails on his 5.5 SL. He was extremely pleased with Chip's customer service and the quality of the sails. They look fantastic.
To me, there are two major considerations:
1) Do you want 'Nacra' sails? If so go with Skip Elliot or Performance sails. I have Performance sails on my 5.8, and they are superb.
2) Price! How much do you want to pay? You will pay a premium for Performance Sails vs. Whirlwind. We will probably go Whirlwind next time, just based on value.
I am sure Gordon will chime in eventually, but here is an image of his Whirlwinds:
