I will have to look into that. I pay for Dive+. I'm cheap! I want more $$$$ for dive trips!!!

For anything not flood-lit, it's crucial to use the manual custom white balance capture feature on the TG, at your planned depth(s). This ability alone dramatically improves TG photos and video, and trounces the action cams for underwater versatility/variable conditions.
Also try turning the 'exposure compensation' down to ~ -0.07 or -1.0. Underwater is generally an inherently dark scene (who knew!)
The preset white balance 'water' modes on all cameras are unreliable and usually inaccurate.
Action cams fail to focus on close subjects or 'macro,' unless you buy add-on lenses etc ($$). TG handles all this internally already
Action cams do shallow blue sandy reefy scenes fine, but go deep or green and it's quickly still trash. You can recover something from 'color-neutral' 10bit action-cam footage, but no guarantees. They do a crap-load of software tricks like denoising/smoothing, exaggerated color shifting and contrast popping etc that work on 'typical' well lit/colored scenes. All small sensors still struggle at depth, regardless of software tricks. New action cams have slightly bigger sensors, but the magic is still digital idealization of limited quality raw data.
The GoPro is a native 7:8 fisheye lens perspective, not rectilinear. Lens correction/stabilization etc should be turned off for underwater if you want the actual image and footage that came through the lens. Underwater, flat port housings will turn what is normally a 'too fisheye' uncorrected land perspective into something more normal underwater. Try this first before buying add-on wet lenses. Stabilize later 'in post'
The inclusion of gyro sensors is the main physical advantage of the action cams, which fuels the advanced but highly-cropped stabilization, but otherwise they are all dramatically less advanced or capable cameras compared to TGs.
