It really depends on what you are wanting to use it for but I do not care for Fitbits.  I wore a two different Garmin watches for about 7-8 years.  They were excellent for exercise and health tracking but have limited ability to control functions on your phone. I now have and Apple Watch Ultra II.  I like it for receiving messages, phone calls, and controlling some stuff on my phone so I don't look at it so often but still prefer the Garmin devices for activity tracking.
