Braid vs Mono vs Fluorocarbon, Honestly
There's no single "best" line — each type trades differently. Monofilament: most stretch, easiest knots, test rating closest to true strength. Fluorocarbon: least visible, best abrasion resistance, stiffer to knot. Braid: zero stretch, thinnest diameter per pound of test, but most visible and worst abrasion resistance.

The one thing to know: A line's printed test (lb) is a manufacturer rating, not a lab-verified breaking point on every spool — braid in particular is very often rated well above its actual diameter-equivalent monofilament strength, so 'test' numbers aren't directly comparable across line types.
Why "test" numbers aren't directly comparable
Braid's material has a higher tensile strength per unit of diameter than nylon monofilament or fluorocarbon, so a "20 lb" braid is often noticeably thinner than "20 lb" mono. Comparing line types by printed test alone hides that difference — compare by diameter and manufacturer spec sheet instead. Related: Is Expensive Line Worth It?.

Frequently Asked Questions
Braid has the smallest diameter per pound of test — a major reason its printed test rating isn't directly comparable to mono or fluorocarbon at the same number.
Fluorocarbon, because its refractive index is close to water's, making it nearly invisible. Monofilament is more visible, and braid is the most visible of the three (usually fished with a fluorocarbon leader in clear water).
Monofilament, at roughly 15-25%. That stretch acts as forgiving shock absorption on a hard strike or hookset. Braid has essentially zero stretch, and fluorocarbon sits in between.
No — it depends on the job. Braid wins on zero-stretch sensitivity and thin diameter, but it's more visible, needs different knots, and has worse abrasion resistance against rock and structure than fluorocarbon.
Very often, yes — pairing a fluorocarbon (or sometimes mono) leader with a braid mainline combines braid's sensitivity and thin diameter with a leader's low visibility and abrasion resistance near the fish.
