Osmo 360 anytime. Been using it for 2 weeks now. Absolutely love the video quality. Especially the night mode on it is really good.
I returned mine because they dropped the price on the 360 to the same price. I kept my action 4 and added the 360.
I have a pocket, action 4 and 360. Each have their purpose. Where any will help over an iPhone the most is audio quality with a DJI mic. In terms of what to buy both the 360 and action can shoot without wide angle distortion. So it’s choosing gimbal and easier selfie recording with the pocket vs waterproof and tough but needing to aim and accessorize more with the action.
What do you actually want from the camera? If it’s to be used as a dash cam, then neither, get a proper system fitted. If it’s for socials or your own enjoyment then option 1, however don’t press record as soon as you sit on the bike, if you’re riding locally you’ll know the good bits, hit record just before then, if you’re out somewhere new, use the road signs to your advantage and hit record when you need to. I record a few of my rides every now and then, either on DJI Action 6, or Osmo 360, depending on what I can be bothered to set up and what I want to capture. The batteries last a long time, I’m not recording the dull section of single carriage way national that’s got solid whites along it and it’s clogged with traffic.
I've been a Pocket 3 user for a while and overall a DJI fan. Once I started looking into 360 cameras though, it was tougher to make up my mind. I ended up buying both the Insta360 X5 and the DJI osmo 360 with the idea of living with them for a bit and eventually giving one of them away to my brother. Both were fun in the initial "honeymoon phase". I’d just shoot everything and figure it out later. But after a few weeks, once the novelty wore off, some stuff I didn’t initially consider started to matter more. Lens protection was a bigger deal than I expected. Since the osmo 360 doesn’t have replaceable lenses, that became a point of concern. I bought lens covers for it. That gave me peace of mind as far as protection, but definitely affected the image quality. This is a major oversight by DJI. Since replaceable lenses became a thing, it's a must-have on 360 cams. What pushed me toward keeping the X5 in the end was the overall experience. Shooting 360 means dealing with a lot of clips, and with the X5, reviewing, reframing, and exporting is easier and less annoying. I had assumed DJI would be stronger on software, but Insta360’s experience with 360 really shows. Desktop editing on both still isn’t great though. The Osmo 360 isn't a bad camera, but when putting them head to head, I kept reaching for the X5 more often. I appreciated being able to focus on what I was recording instead of worrying about breaking the lenses or bad image quality from lens guards or how to deal with the footage afterward. I'm curious to know what the community thinks. Have you compared these two models, and what ended up mattering more to you?
Osmo 360 anyday. Using it since 6 months. It has Biggest sensor, excellent in low light.
I’m a DJI guy mainly, so you asked the right person. IMO, there is not a huge difference in video quality between them. I went with the 360 because all my current accessories and batteries work with it. It was waaaay cheaper since I’m reusing a bunch of stuff between my action cam and my 360 cam. If I was coming in brand new, I’d go with the X5 for the user replaceable lenses alone. But, the 360 is a little cheaper right now and lens covers aren’t very expensive and don’t negatively affect camera quality very much.
