A lighter running watch against a rugged multisport watch with a flashlight and dive rating.
Verdict
Buy the Forerunner 965 if you mainly run or race: it is lighter, costs far less, and gives you AMOLED, maps and the same core training metrics. Buy the Fenix 8 only if you want a rugged outdoor watch with a flashlight, dive rating, speaker and longer battery life. Most runners should pick the Forerunner.

Running or triathlon is your main sport, you want a lighter watch for long runs, and you do not need dive support or a built-in flashlight. It delivers training readiness, running power and maps at a much lower price.

Skip both if you only want basic run tracking (a simpler Forerunner costs less) or if you prefer a lower-cost watch from another brand; the Forerunner and Fenix are both premium-tier watches.
Forerunner is Garmin's running-focused line: lighter and cheaper. Fenix is the rugged multisport line with more outdoor features, such as a flashlight and dive rating, and a higher price.
Only if you also want the rugged features. For road running and racing, the Forerunner 965 gives you the same core training tools for much less.
The Fenix 8 lists up to 47 hours in GPS mode against up to 31 hours for the Forerunner 965. Both last for days or weeks in smartwatch mode.
Yes. Both use AMOLED displays, which are bright and easy to read, with some effect on battery when always-on is enabled.
