Visit COROS ↗QUICK VERDICT
Choose Garmin for coaching and wellness. Choose COROS for running hardware value.
The Forerunner 165 is friendlier for a first-time sports-watch buyer who values adaptive guidance and Garmin's broader wellness ecosystem. The PACE 4 is the stronger pure-sports package, pairing an AMOLED display with dual-frequency GPS, much longer tracking time, multisport support, and local MP3 playback.

GARMIN WINS
Display and everyday experience
The Forerunner 165's AMOLED panel is sharper, brighter and more smartwatch-like. That makes maps, workout prompts and daily metrics easier to read indoors and in mixed light. It also adds Garmin Pay; offline music is available if you buy the Music version.
The trade-off is battery consumption. Garmin claims up to 11 days in smartwatch mode, dropping to four days with always-on display enabled. TechRadar reported roughly nine days with regular GPS use, but individual settings can change this substantially.
COROS WINS
Battery, GPS and low weight
PACE 4 now uses AMOLED too, so choosing COROS no longer means accepting a basic MIP screen. COROS claims up to 41 hours in All Systems (High) GPS mode and up to 19 days of daily use.
At 32g with the nylon band, it remains exceptionally light. The gain over Garmin is less about display quality now and more about endurance, dual-frequency positioning, multisport support, and sports-first efficiency.
GPS accuracy: closer than the spec sheet suggests
The PACE 4 has the technical advantage because it offers dual-frequency GNSS. Tom's Guide reported excellent tracks against established reference watches, while OutdoorGearLab measured 2.02 miles on a two-mile course and praised its track shape through demanding terrain.
However, the Forerunner 165 should not be dismissed because it lacks dual-frequency mode. DC Rainmaker's comparison traces and OutdoorGearLab's hill and track testing both found it performed well. For normal road running, either watch is likely sufficient; dense high-rise streets and difficult terrain give the COROS mode the clearer theoretical advantage.

Which should you buy?
Buy the Forerunner 165 if…
- You want an attractive AMOLED screen.
- You are new to structured training and value Garmin Coach.
- You want contactless payments.
- You already use Garmin Connect or other Garmin devices.
- You prefer a richer health and lifestyle ecosystem.
Buy the PACE 4 if…
- You want maximum GPS battery for the price.
- You run long events or dislike frequent charging.
- You want dual-frequency positioning and multisport support.
- You want local MP3 music without carrying a phone.
- You prefer an ultralight AMOLED sports watch.
BOTTOM LINE
The Garmin is the friendlier ecosystem; the PACE 4 is the stronger sports specification.
Start with Forerunner 165 if coaching prompts, health context, Garmin Connect, and optional streaming-service music matter most. Choose PACE 4 if dual-frequency GPS, far longer tracking, multisport use, local MP3 playback, and low weight are higher priorities.
Prices and firmware change. Compare the current regional price before deciding: a meaningful Garmin discount can strengthen its case, while the COROS advantage is clearest near regular retail pricing.
