Growth against the P/S 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.

OGSONE Gas, Inc.
Utilities - Regulated Gas · $72.50 · beta 0.63
Why now
Utilities - Regulated Gas · market cap $4.6b. Down 20% from 52-week high of $90.78 — deep drawdown territory. Revenue growing +43% — in hypergrowth territory. 9 sell-side analysts rate this a Buy with a mean 1-yr target of $86.17 (implying +19% upside).
Moat
Higher-variance name — the moat signals on the quantitative card are modest, so the durability case rests on execution (turning current growth into durable earnings power) or an un-monetized asset (IP / network effects / first-mover position) rather than an entrenched competitive position.
Risk
Free cash flow is negative (-$173m) — capital raises or debt issuance likely required; dilution / leverage risk. Jurisdictional + permitting risk — mining and extraction operations concentrate exposure to political stability, royalty regimes, and environmental review timelines that can stall production for years.
SOThe Southern Company
Utilities - Regulated Electric · $86.17 · beta 0.30
Why now
Utilities - Regulated Electric · market cap $99.1b. 15% off the 52-week high of $100.84. 19 sell-side analysts rate this a Hold with a mean 1-yr target of $98.13 (implying +14% 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 11% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere. $99.1b market cap gives the company enough scale to absorb fixed costs that subscale competitors can't, without yet being so large that growth has to come from acquisition.
Risk
Free cash flow is negative (-$3.5b) — capital raises or debt issuance likely required; dilution / leverage risk.

Where OGS and SO diverge
On the headline score the gap is 16.3 points in favor of OGS. They get there differently, though — each leads on a different pillar, so the better pick depends on which you weight.

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 OGS or SO the better stock?
OGS scores higher: OGS 67.7, SO 51.4 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 OGS and SO differ most?
The widest gap is value, where OGS leads by 46 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 OGS and SO 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.
