Side by side · every name on one set of axes
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.

Winner per row is the stronger grade; where grades tie, the better figure breaks it. A true tie or a missing value shows no highlight.

These two disagree on this pair: the Value pillar ranks cheapness against sector peers, while price-vs-fair-value is an absolute read. A name can be the better value in its sector and still the dearer one on cash flows.
The DCF is a cross-check on intrinsic value, separate from the quality-growth score above.

The companies
ZZillow Group, Inc.
Internet Content & Information · $29.01 · beta 2.02
Why now
Internet Content & Information · market cap $6.5b. Down 63% from 52-week high of $79.40 — deep drawdown territory. Revenue growing +18%, comfortably above the S&P median. PEG 0.93 — paying under fair value for the growth rate. 6 sell-side analysts publish a mean 1-yr target of $46.00 (implying +59% upside).
Moat
Free cash flow runs well ahead of reported net income.
Risk
Trailing P/E 126.1x prices in sustained high growth — any quarter that disappoints triggers sharp re-rating. Down 63% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 2.02 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return.
GOOGAlphabet Inc.
Internet Content & Information · $347.86 · beta 1.21
Why now
Internet Content & Information · market cap $4.3T. 14% off the 52-week high of $404.47. Revenue growing +20%, comfortably above the S&P median. 14 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $420.36 (implying +21% upside).
Moat
Net margin 55% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 38% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. $4.3T market cap places it among the largest companies in the sector — distribution, R&D, and customer-acquisition costs amortize across a base peers can't replicate.
Risk
Mature compounder — the risk is paying up for quality at a moment when growth is decelerating. Watch for sequential revenue + margin trends; the inflection from "compounder" to "ex-compounder" is hard to spot until the multiple already started compressing.

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 GOOG or Z the better stock?
GOOG scores higher: GOOG 80.4, Z 38.0 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 GOOG and Z differ most?
The widest gap is quality, where GOOG leads by 50 points on the 0–100 pillar scale. GOOG leads all three pillars, so the gap is broad rather than a single-measure difference.
How are GOOG and Z 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?
