Proof is in the pudding as they say.
If triangle barrels were better you would see the benchrest crowd using them.
As far as I know they are not. Now I do not follow the benchrest crowd so I may be wrong, but if there was ever a group of firearms people more willing to do anything to get the most accurate firearm, I sure do not know about them. I would find a benchrest forum and post your question to them.
