Forerunner 255 Series
Long battery; but wrist HR tracking is inconsistent.

That month doesn't include hours of tracking each day. That will cut it down to about a week or less. (Source: Garmin Enduro 3 owner)
I got the Enduro 3 with a 20% off coupon by downloading the Optimity app and playing Yatzee until I had enough points for the Garmin coupon. It brought the cost below $800 including tax.
I ended up going with the Enduro 3 from a Fenix 6 for the reason you stated. I didnāt need the dive feature and speaker as well
I went from an AW to first an Epix pro gen 2 and then an Enduro 3. Although I did like Siri on my wrist, I can still change my music from my current Garmin, and see the notifications Iām getting so I feel Iām not really missing much. I prefer to type on my phone anyway as Siri isnāt the greatest at making words work haha I find the battery life, the durability and just « this is a watchĀ Ā» of the Garmin will keep me. I donāt have a mini phone on my wrist and my eyes prefer the MIP screen. And then thereās the flashlight function. My god what a game changer and so practical, from checking on kids at night to looking for things to doing work with tools. I find I donāt baby my Garmin as much because Iām not worried about smashing the screen or scratching the finish. Thereās also less of a concerns for me personally for water damage and something about physical buttons that I love. Thatās all I can think off the top of my head, but Iāll never go back to AW and Iām very much ingrained in the apple ecosystem in all other areas.
If u want only a watch: your best take is the Enduro 3. If you want a 'computer', Look at the Edge models Like 1040 (mip Display) or 1050 (amoled Display)
No, Enduro 3 has the longest battery of all of them. "Better" is relative and what do you mean by "performance oriented"? It will help if you can describe what kind of activities you want to do and what expectations you have from the watch.
