I've used the Garmin Vivoactive and Vivoactive 3 for the past few years and this is a better watch for running, particularly because it uses buttons rather than touchscreen controls during a run. The Vivoactive had to have the screen locked manually if running in even the lightest rain and this made it more difficult to operate on the run.
There is more than enough info recorded for me and the data screens were a bit fiddly to set up but then I found it was easier and clearer to do them via the phone app. The longer battery life is great and although I still need to spend some time customising it I'm very happy with the purchase.

Very happy with purchase
Excellent price and fast shipping from Fitness NZ. The strap is more comfortable than I was expecting. Keep in mind 2 things, this model can only display 4 fields at a time on one data screen, vs the Forerunner 265 which can display 6 (but the 165 is several hundred dollars cheaper), and it seems Garmin devices come with a USB-C charger cable so if your regular charger outlets are USB you'll need to buy a different charger cable. Overall, for the price this Forerunner 165 tells me everything I need for running (I have an Edge 530 for the bike already) and general exercise and I'd highly recommend it for the recreational to moderately serious athlete. I'll probably end up using this Forerunner for cycling too because it doesn't require wearing a HR chest strap.

Great first running watch
I don’t have a lot to compare to with this being my first running watch. But I love it.
So many good insights into my running. Updates to my Strava without any effort. Has upped my motivation to improve and I can see that in real time.
Battery is great and means I can leave it on all week without any concerns, while going on several long runs.
I’m sure one day I’ll look at higher spec versions, but right now it gives me more than I need and lets me feel out on how I’m doing!
