Great low-light, mic integration; watch out for lens flare.

You will not notice a difference in video, especially at 4K. Mission will appear more detailed. The only time you will notice a difference is shooting at 50MP and zooming to 400%. Not the case for video.
Have a Hero11 Black. It works great. I've used a GoPro Max for action sports outside the water. I really love that camera, but I've heard it's not so good for underwater shooting.
The 11 is great, don't over think it. Buy whatever is in your budget, 11 is great due to the front screen and quality is great too.
Same here! Do got the media mod, it makes a ton of difference in the sound. Be aware that all the previous generations weren’t that good in low light. If it is for vlogging, there is a light that attaches to the media mod, so he’ll be sharp. The ones that were just announced are supposed to be better in that regard. However I also have a Osmo Pocket 3, the bigger sensor ís better, but it’s still physics and a lightsource is simply better. Very nice to gift him this camera
I have a GoPro 9, 10 and two 11’s and had a DJI Action 4 at the end of last kayak fishing season. I don’t care how anyone regards GoPro in relation to DJI or Insta360, I care about my own experience. I chose to stay with GoPro. Edit: I forgot that picked up a GoPro Max on super deep discount at Best Buy after I decided to sell my Action 4 and stay in the GoPro camp.
My 9, 10 & 11 are awfully good to me.
Personally I'd rather have two used Hero 11's than a single Hero 13. Whilst things like the magnetic mount are convenient, having two cameras offers a lot more flexibility. Eg, leaving one rigged on the bike full time, and having another to use for scenery, pieces to camera, etc.
Get whichever Go Pro is in your price range. Anything Hero 7 and above will have hypersmooth and as long as you’re not running it at max resolution and fps it shouldn’t overheat, especially with a fan or AC on in the car. 30 fps would be my recommendation, and most should be able to handle that at 4K just fine.
