Growth against the P/E multiple. Up and to the right is cheaper and faster — the quality-growth idea in one picture. Points beyond the axis are pinned to the edge and marked off-scale rather than allowed to compress everything else.

The companies
AMCRAmcor plc
Packaging & Containers · $41.72 · beta 0.58
Why now
Packaging & Containers · market cap $19.3b. 18% off the 52-week high of $50.94. Revenue growing +57% — in hypergrowth territory. PEG 0.96 — paying under fair value for the growth rate. 12 sell-side analysts rate this a Buy with a mean 1-yr target of $49.76 (implying +19% upside).
Moat
FCF converts 111% of net income — earnings translate cleanly into cash.
Risk
Dividend payout 109% of earnings on a 6.2% yield — distribution coverage is thin; one earnings stumble could force a dividend cut. Net margin 4.7% is thin — operating leverage cuts both ways; input-cost inflation or pricing pressure hits the bottom line first.
SONSonoco Products Company
Packaging & Containers · $47.92 · beta 0.33
Why now
Packaging & Containers · market cap $4.7b. Down 21% from 52-week high of $60.67 — deep drawdown territory. Revenue growing +31% — in hypergrowth territory. PEG 0.21 — paying under fair value for the growth rate. 9 sell-side analysts rate this a Buy with a mean 1-yr target of $61.11 (implying +28% upside).
Moat
Net margin 14% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 28% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which.
Risk
Value re-rating depends on a catalyst. Without one — analyst day, divestiture, margin recovery, capital return — the stock can stay cheap on these multiples for years.
Verdict — model-derived comparison
SON leads AMCR by 0.7 points (69.2 to 68.5), its sharpest advantage coming in P/E (grade A). A contrarian could still prefer AMCR, which trades about 37% below our DCF fair value — a margin of safety the score doesn't reward.
Our AI analyst is busy right now, so this verdict is drawn directly from the pillars, grades and DCF above.

Pillars run 0–100. Value is judged against each company's own sector, so a Value score is a statement about a company relative to its own industry rather than to the other name here. A wide Value gap usually means the market already prices the difference in quality or growth — which is the trade-off this comparison comes down to.
Common questions
Is SON or AMCR the better stock?
SON scores higher: SON 71.7, AMCR 70.9 out of 100 on the Bull Rankings quality-growth score, which blends business quality, growth and valuation into one number. A higher score means a stronger business at a more reasonable price — it is not a price target or a recommendation.
Where do SON and AMCR differ most?
The widest gap is quality, where SON leads by 10 points on the 0–100 pillar scale. Neither name sweeps: they trade the lead across the three pillars, so the comparison is a trade-off rather than one being better on every measure.
How are SON and AMCR scored?
Each carries the same 0–100 quality-growth score used everywhere on the site, built from three pillars — quality (profitability and returns on capital), growth (revenue and earnings), and value (what you pay for them) — combined as a geometric mean, so a weak pillar cannot be papered over by a strong one.
How current is this comparison?
The whole universe is re-scored every trading day after the US market close, so the scores and fundamentals here reflect the latest published edition.
