I started with a wrist caliper release and it was very accurate trigger, with a light crisp trigger. That said it was cumbersome to use and not hunting friendly for me.
I tried a thumb release but just didn't work well for me.
I went with a Scott hook wrist release, I hunt coyotes with my bow and It frees up my hand to run an e-call or mouth call and can quickly draw the bow for a shot.
My bow is quite short which really eliminates using a finger release.
My bowfishing bow is a longer recurve and there I use a finger release as any kind of release hanging off my wrist gets in the way retrieving line and a thumb release would bound to end up in the drink if I had to lay it down every time I shot the bow.
