I would suggest that most FAC owners with a few exceptions have little comparative experience of different moderators, unless you are/ work for a RFD, this is in part because of our firearms law, once you buy one it is a pain to change it.
In addition people lose a bit of their subjective ness once they have brought there chosen model , hence in the pole they vote for the model they own, to do other wise would be to admit they have made a mistake.
I note that there are people voting for a moderators as the best one when they are being massively over charged for the said item. Others are voting for the biggest heaviest moderator on the market neither of the models offer any advantages over other cheaper lighter better made moderators that are available. The situation is not helped by some of the top writers for gun magazines being very very friendly with some of the major importers of moderators. This makes it difficult for you to not question the objectiveness of their reviews.
If you do your research carefully, compare weight, construction, adaptability and price you will find there are may be 3 or 4 models that are far superior to the rest and which is best depends on what characteristics you value most in a moderator.
