Stookeyfpe: Thank you for your response.
NFPA 15 neither talk about difference between nor suitability of those nozzles.

Why don't you just consult the manufacturer literature? Just by studying them you can get valuable information about their differences.

more specific information is hard to provide through a forum as the design criteria that affect their choice are strongly related to the specific application you have.
