I don't know how so many portfolios could be better than the readers given two things:
1) The readers' portfolio probably very closely approximates one of them, and
2) Many of the portfolios premises conflict with each other.
Is 100% BRK > PP > 100% Vanguard S&P > "your" portfolio?
IDK how you'd rank these, besides personal preference (and hindsight), so I don't know how the author can claim anything close to the title of the piece.
No deep analysis on any of these, so I'd imagine for someone starting out, this contains very little useful information. I'd rather see 3-4 different strategies compared and analyzed and discussed who should be investing in each, and why, than just listing a bunch of popular portfolios, personally.

YMMV. :)
