I think the problem comes when opinion is presented as fact.
For example, I can say...
The Travel (small elasticized donut) wing is the best wing.
The Rec (bungee) wing is the best wing.
The Classic (non-bungee) wing is the best wing.
To me all three statements are true, depending on the circumstances. But they are really just my opinion, based on my experience, my preferences and my ability.
Some would dictate how others dive, or at least attempt to elevate their own diving style by denigrating all others.
I'm a fan of freedom. Try what you can, dive what you like.
