I'd never recommend you buy the Insta360 Link 2C at full price. That's not because it's not worth the $150 asking fee, but that, in the months I've been watching its stock, it has sold for $100 / $110 almost as much as it has $150. Though it's not on sale right now, I've seen it discounted at both Amazon and Best Buy multiple times over the last few months. At this price point, I can't recommend a single 4K webcam on the market over this one, assuming you'll actually get the use out of 4K.
4K is still a bit of a niche even now. Some software doesn't support it, and others (like Discord) require you to have access to a subscription for 4K webcam streaming. Even if your software supports 4K resolution, a small cam on top of a stream on Twitch or YouTube generally won't justify such a high resolution.
