I love the Insta360 cameras, I have the One X, One R and One X2 and used to have the GoPro Max. I've not posted any footage from them recently as I was having memory card issues, hopefully they are sorted now so can start using them again more regularly.
I think as a second camera they are great, but currently only as a second camera. I prefer the Insta360 products, but the GoPro Max is a great camera too.
Generally I use the One R when riding my dirtbike as it has strong lens protectors, and the One X2 on my road bikes. I've loaned my One X to another motovlogger. I personally didn't get on with the GoPro Max, mainly that was due to it not having a bundled editor for PC when it came out, which made editing the footage from it hard to do, GoPro have now sorted that, but I still think the Insta360 PC software is better.
@Drakhen99 edits all his 360 stuff on Davinci Resolve iirc, so he doesn't have the issues I did.
