Is the COOSPO H9Z Heart Rate Strap any Better Than My Garmin Watch?

Is the COOSPO H9Z heart strap worth getting when I already have a heart rate monitor built into my Garmin Vivoactive 4 watch? This video will take a look at my first time using a heart strap compared to my optical wrist based HRM in my Garmin watch. I conduct tests during a zone 2 ride outside, a spin class and a walk/run interval workout. #heartratetraining #coospo #garmincycling #garminvivoactive4

Thanks for this Steve. I've been curious about the difference between the two for a while now.
I think I will stick to my wrist based watch, I've so far just been wearing my Fitbit but I'm less concerned about the other details which the Fitbit provides these days so I'm considering investing in something like a Garmin.
Do you have any thoughts about the comparison between the Fitbit and Garmin brands in terms of HR accuracy?
Thanks!
Edit - For context I do daily Z2/3 cardio indoor for 30 minutes only.
Edit 2 - Sorry I might have missed it but which garmin watch do you have?
