I'd like to get an action camera before I go fly fishing in Chile in March 2026. These seem to be good options. Anyone have an opinion on one vs the other? Thanks.

I don't have personal experience, but have heard that newer GoPros have not been as good as their overseas competitors. That's being said, I bought an old GoPro from eBay years ago, and it does well. Still use it and have no complaints, but I'm also not doing any super fancy high quality video editing.

Use it for snorkeling, flying, shooting. The eBay deals often come with accessories and are pretty solid. Or was for me.

I had a GP 8 or 9. While I liked both the video quality and the form factor, if you will, I hated the fact that it was like disassembling a car engine to get to the SD card. Heaven forbid you had additional mods (I had most of them -- light, media, etc.). The upload of videos to the GP site (additional cost) didn't work because it was app based. It had several limitations, though I don't recall all of them. I finally sold the system after about 2 years and went back to a 3 tier approach: my fairly recent iPhone Pro, an early generation Pocket Osmo, and my Panasonic GH4 when needed. I will probably upgrade the DJI at some point, perhaps next summer. I don't really have the need for a waterproof solution.

I would recommend getting your hands on one of these and figuring out prior to purchase whether what's required of your workflow will be something you'll dread.

I'd go DJI. The GoPro's overheat easily. I've been on several shoots where the Osmo Actions far outlasted the GoPro's in direct sun. And that was previous version of each.
