IMO, i think that for the average player, a triangle tip is good enough.
I think that for the average Pro, a triangle is good enough. I think for a world champion it's also good enough.
My opinion is that if you can't play with a good single layer tip, no $20-$50 tip is going to make you a better player.
It seems that far too many people can't or won't do basic tip maintenance but it's was a great business decision to charge a 40x markup for a layered tip over the cost of a good single layered tip.
It's only money, if it makes you feel better or gives you more confidence buy it.
