Our top picks

Most runners should get the Garmin Forerunner 165. It costs less, has more smart features, and has many more owners behind it. Get the COROS PACE 4 if you want the lightest watch, the longest battery and dual-frequency GPS.

We compared the 43 mm Forerunner 165 and the PACE 4. Both are mid-priced running watches with a 1.2-inch AMOLED touchscreen and built-in GPS.

What owners complain about

  • On the Garmin Forerunner 165: settings that change after updates, Bluetooth that disconnects, battery that drains with activity, and charging contacts that collect grime.
  • On the COROS PACE 4: spotty heart rate during intervals, a small screen, sleep tracking that misses when you fall asleep, and fewer smart features.
  • On both: no critical review was visible on either page, so complaints are mild.

What we left out, and why

We read two listings and 16 reviews.

  • Garmin Forerunner 265 and 570. Higher-priced Garmins. Our Apple Watch vs Garmin guide covers the 265.
  • COROS PACE 4 Pro, PACE Pro and Vertix. Higher-priced COROS watches.
  • Forerunner 165 Music. A separate style with music storage. We read the Standard.
  • Renewed watches. Not new, so they are not a pick.

How we researched

On October 14, 2026 we read the Amazon listing pages for the Garmin Forerunner 165 and the COROS PACE 4. We read each page's bullets and specs, Amazon's review summaries and the reviews we could see. We also read WeeViews' Coros vs Garmin comparison and checked Google's top results for this question. AI wrote this guide from that research.

The Garmin listing gave no weight or water rating. The PACE 4 listing is newer, with far fewer ratings, and neither page showed a critical review of 1 to 3 stars, so the complaints are milder than a bigger sample would show. The Forerunner 165 reviews may include its Music version. WeeViews compared the two brands' 2025 lineups, so we use it for how the brands differ.

Prices, ratings and review counts come from Amazon and were read on October 14, 2026.
