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

Hero 3 Silver has a special place in my heart. Hero 5 was the first to really WOW me.
I've got a Hero 11 and a Max 2. I used to own a Insta360 x5 and a go 3s. GoPro has done a good job of engineering the cameras to be fairly rugged and work under difficult conditions (more so than Insta), and while the quality isn't there for low light, I've been ok with that, because it constitutes a small fraction of what I want to video. I particularly like the GoPro buttons, which I feel work better when my hands are cold. Plus, I do a lot of editing on Quik now, which works and does the minimum I need.
Agreed with your first point (but I think, since the Hero 3, I have used my cams once in the dark) Agree with the second point but I like to use the best options available to me, no matter what brand it may be. If that means using insta’s software to edit my GoPro footage then so be it. But then, you went full Tropic Thunder…
Plus one for the action cams. I don't know about the knockoffs, but there's plenty of GoPro knockoffs with durable cases. And you can find a used GoPro Session in the $60 range. Even a Hero 3 is still a decent option over a toy camera.
I have you beat, I'm still using a GoPro 3, lol. I keep thinking I want to buy a real camera but I just don't. Went diving last weekend and someone from the dive shop brought a Divevolk for iPhone. It was reasonably descent but not great. He didn't have any lights and we were diving in 3 to 6 meters of water. Looked very grainy compared to someone who had a DJI Action 4. Personally, I am thinking about the DJI Action 5 now. I looked at the Action 4 but in a side by side comparison I found: * Action 5 did 240 minutes, Action 4 was only 160 mins * Action 5 had subject tracking, Action 4 did not * Action 5 has an OLED display, Action 4 has LCD (I prefer my dive computer with OLED over older LCD display, so probably similar for camera) * Action 5 has a built-in pressure gauge and 47 GB of storage, Action 4 has no built-in pressure gauge or storage * Action 5 is 40 MP resolution, Action 4 is 9.98 MP If I didn't go for the Action 5, I'd probably look at the Action 3. It is similar to the Action 4 but cheaper.
I still have a 4k GoPro hero 3 from like 15 years ago and it works very well. Crazy that it regressed.
