Yes! GoPro, like Walkman before it, has become the de facto name for a product category, but others offer good alternatives. GoPro is especially vulnerable in the area of 360 cameras (see our 360-degree cameras guide), while DJI has interesting premium action cameras. Check our whole best action camera guide to see comparisons. I'd say that the DJI Osmo Action 4 Pro is now the best action camera because it has a bigger sensor which is better in low light (if you're surfing in the sun, however, that advantage might be moot).
