Pros & Cons
COROS PACE 4 (silicone band)
Pros
- +Dual-frequency L1+L5 GNSS at $249 — the single biggest accuracy upgrade you can buy at this price
- +31 h in the most accurate GPS mode still beats what most $500 AMOLED watches manage
- +32 g on the nylon band; you forget it is there on a long run
- +No subscription anywhere in the COROS ecosystem, and .FIT files sync free to Strava and TrainingPeaks
- +DC Rainmaker found the optical HR 'spot-on' through intervals — unusual for a $249 watch
Cons
- −No offline maps at all — breadcrumb trails only, which is a real limitation off-road
- −No ANT+, so ANT+-only power meters and older chest straps will not pair
- −Music is sideloaded MP3 only; there is no Spotify, no streaming, no phone-music control
- −Always-on display costs 13 of the 19 claimed smartwatch days and 10 h of GPS time
- −Training Load resets every Monday rather than rolling, which DC Rainmaker notes does not match recovery physiology
Suunto Vertical 2 (stainless steel)
Pros
- +65 h of dual-band GPS on an AMOLED watch — no other AMOLED here comes close in the accurate mode
- +Free worldwide offline maps in 32 GB, downloaded straight over Wi-Fi with no cable and no charge
- +A bright LTPO AMOLED behind sapphire, plus a bezel-integrated flashlight, for $599
- +DC Rainmaker rates GPS accuracy excellent across difficult terrain
Cons
- −87 g in the steel version reviewed here — the titanium at $699 saves 13 g
- −No music storage of any kind on a $599 watch
- −Only about 10-12 routes can be stored in practice despite 32 GB, and turn-by-turn needs manual enabling for imported routes
- −Real-world dual-frequency runtime with always-on and navigation running measured about 50 h, not 65 h
- −Bluetooth only — no ANT+ sensor support
