The Verdict: They Look at Both
Colleges generally view your application "holistically." This means they use both numbers to answer two different questions:
Answers: "Is this student a consistent high-performer in the classroom?"
Answers: "Did this student challenge themselves with the hardest courses available?"
It Depends on the School
Not all admissions offices use the same formula. Here is how the three main categories of universities usually prioritize your GPA.
Ivy League & Top Tier
Focus: Extreme Rigor (Weighted)
They expect a near-perfect Unweighted GPA AND a high Weighted GPA. If you have a 4.0 Unweighted but no AP classes, you are likely at a disadvantage compared to a student with a 3.9 Unweighted and 6 AP classes.
State Universities
Focus: Formulaic / Index
Large state schools often use an "Admissions Index" that combines your GPA and test scores. They often strictly use the Weighted GPA reported by your school to rank applicants efficiently.
UC System (California)
Focus: Recalculated Capped
Schools like UCLA or Berkeley completely ignore your school's GPA. They calculate their own "UC GPA" which limits the number of extra honors points you can receive, essentially leveling the playing field.
Check Both Scores Instantly
Don't rely on guesswork. Enter your grades once and see your Weighted and Unweighted GPA side-by-side.

The Bottom Line
You should never lower your standards to protect your Unweighted GPA. Taking a rigorous class and getting a 'B' is almost always better for admissions than coasting through an easy class to get an 'A'.
