Question about Brio Stream - 433981

A webcam that triggers a lot of questions in me. There are somehow 3 different products, but technically they all have the same specs, but the prices are extremely different. From currently CHF 165 to CHF 329. On the official Logitech website it is also not decipherable. - Logitech Brio 4K - Logitech Brio Stream - Logitech Brio 4K Stream Edition I'm looking for a webcam and the Brio 4K is definitely on my shortlist. However, the whole thing is confusing the heck out of me. Does anyone have a type for me? Thank you very much!
