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.

Scientific & Technical Instruments · market cap $51.8b. 15% off the 52-week high of $314.28. Revenue growing +16%, comfortably above the S&P median. 6 sell-side analysts publish a mean 1-yr target of $302.00 (implying +13% upside).
Moat
Net margin 23% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. ROE 19% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately. $51.8b 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
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.
Scientific & Technical Instruments · market cap $17.9b. Down 41% from 52-week high of $447.62 — deep drawdown territory. Revenue growing +16%, comfortably above the S&P median. 14 sell-side analysts publish a mean 1-yr target of $410.86 (implying +55% upside).
Moat
ROE 15% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere. FCF converts 103% of net income — earnings translate cleanly into cash.
Risk
Down 41% 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. Trailing P/E 42x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.

Where GRMN and MKSI diverge
On the headline score the gap is 10.2 points in favor of GRMN. They get there differently, though — each leads on a different pillar, so the better pick depends on which you weight.

ValueGRMN 39.1 · MKSI 35.9GRMN +3.2
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 GRMN or MKSI the better stock?
GRMN scores higher: GRMN 65.0, MKSI 54.8 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 GRMN and MKSI differ most?
The widest gap is quality, where GRMN leads by 32 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 GRMN and MKSI 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?
