Should I buy the FR265 or FR965

I don't own a Garmin but looking to get a FR. I am a runner, training towards half marathon. I do own a Fitbit charge 5 at the moment but I want to upgrade to an actual watch and after a few years with Fitbit, I notice that Garmin might be the better solution.

My idea was to get a 265 for around 300€, but then I saw the 965 was 454€. Naturally I thought to myself: more expensive is probably better, but I am having a hard time trying to find an easy "Garmin beginner" video or explanation to decide what I should do.

The amoled screen is a difference, it is bigger and it has the map feature that I know of but it's that enough to justify the price tag?
