Alex, we've been through this before. There isn't a "BEST". Everyone has different opinions on what works best for them. You will get many different responses. A good way to narrow down your choice before making a purchase for any type of magic effect is to read reviews on many different magic sites / forums. You'll need to factor in cost, practicality, angles, reset, etc.
Simply "telling" people to answer the title to your thread seems a bit lazy on your part. Sorry if that hurts your feelings, but that is the truth.
