I was from fitbit before AW, the benefit to me is the health metrics (fitbit need subscription for more details and past history data) ....and you can install other apps if you want more analysis from your AW. (Fitbit can't do this).

distraction from screen is not a problem to me... because i have a clear goal of wearing AW.

The Sleep tracking is efficient for me to understand how my day will be affected and i can be more alert on my approaches.

Mindfulness is an underrated apps which many dont find it usefull, but for me i find it important as it managed to capture my stress moment and put up a notifications requiring me to take a short break or perform better management for the situation. It can also predict if u fall into hard moments. So far its all accurate.

Other than that, the active rings are alwis visible to keep track on the daily goals.

One thing, to fully utilize the full feature of AW, must get the cellular version. Its actually very convenient without the phone. I have less time with the phone now, hence reduced up to 50% of my phone screen time. Once u get the grip of responding to msg, calls and notification on the AW, the phone is just another bank token and double as tablet.

ApplePay never disappoint, i am able to transfer up to 90% of  retail transactions from eWallets to ApplePay. Banks give rebates as well (SC and MBB) for ApplePay usages. Best part, even with transaction above RM250 dont require to key in pin numbers on the device, just tap and go. Effectively reduce the unnecessary contacts, and hassles free from topping up eWallets and key in pincodes. It just work. Apple Pay is safer as the transactions perform on ur credit card dont reveal ur actual credit card numbers, it will show smth different to the merchant and receipt.

Other then what have been mentioned by others i like the feature where it notify you when there is a change in the trend of your health metric. Example when ur breath per min increase reduce it will notify. Your steps trend change will also notify.
