Eufy vs Tapo vs Reolink

I know these posts come up all the time (sorry), but I guess everyone has different requirements. I am based in the UK and the security ecosystem must be:

- affordable and designed for home use, not business use

- Wifi cameras with battery (at least at first, it's not fort knox)

- can integrate with Alexa / smart systems (although I am not interested in the Home Assistant, it's just ANOTHER thing to maintain **\* )

- able to capture footage without a monthly subscription. The footage must be saved locally by SD card or internal storage, and must be able to be viewable via smart phone app when away from home. I know Eufy's cameras require a Hub, but I think it's more likely something happens to the Hub (e.g. theft) than the SD card inside the camera.

I am looking for one ecosystem, and need a smart doorbell too. Reolink's doorbell is laughable from what i've seen, I was leaning towards Tapo D235, but then are the Tapo cameras good?

***I would be interested in setting it up on a raspberryPi or something, but isn't it more likely the Pi fails than Eufy/Tapo/Reolink's network? My router also doesn't support VLANs, the best I can do is put it on the Guest network with WPA2 protection.
