I’ve had the Arlo ultra 4K for over a year and it’s alright. Not sure I would buy again. The software is buggy and the support is pretty much non-existent. Also, the Arlo ultra isn’t a HomeKit Secure Video Camera if that matters to you. There were problems selecting the different side-angle options and activity zones weren’t reliable. The battery life didn’t live up to the advertised claims either. I didn’t renew the service after the first year and I get a giant promo to subscribe every time I try viewing my camera feed.
Considering how much it costs I would look into a eufy or other alternative. I have a nest too but I don’t like how it sends the video to the cloud before you can see it locally.
