Best new smartwatch as collector with strongest vibrations

I have miaomiao2 with libre and find that vibration works much better to wake up for lows and highs . I tried a kospet prime se standalone android and found that the vibration was weak ,the alarms were inconsistent and the missed readings with both xdrip and glimp. Tomato couldnt be resized to see the bind screen.

1-Was wondering if people could comment re what new smartwatch has the best performance for a collector

2-has the strongest vibration.

3-According to the xdrip site only watches that have wear os are supported
Can people comment on the reliability and xdrip support for fitbit versa or samsung smartwatches on tizen os

Thank you for your help
