Best smoke detectors?

About 7 years ago I installed a bunch of Mitre10 / Bunnings smoke detectors which seem to work well, hardly false alarms, 9v batteries last ~2-3 years I've now found out they are ionization alarms and they are no longer recommended. Also, Fire NZ recommends fire alarms with 10 years batteries built in. I checked both Bunnings & Mitre10 and most of them get crappy reviews.

On Reddit I saw that Cavius is recommended a lot, but they also get bad reviews on Noel Leeming that they stop working after <5 years. However, they have a 10 year warranty, so I guess in such cases I would get a new one? They cost ~$50 at NL, and I know not to always trust their pricing, is there a better/cheaper shop to buy them?

Or should I buy a different brand? I also see good reviews about Nest Protect. A lot more expensive, but I like that I can connect them to Home Assistant. However, I can't seem to find them available in NZ. Some other post suggested these from Aliexpress A bit reluctant to get smoke detectors from Ali though.

I know 220v connected ones are better, but as we'll be selling the place most likely within <10 years, not worth the extra $$.

Most of the ones that you can buy from big box stores will do the job as from what I recall to be approved for sale in NZ they have to conform to fire safety standards.

If you are planning on selling eventually, spending a bit more now for the 10 year battery versions might be a good investment.

Cavius 10 year battery ones, Advance electrical and J A Russell carry them.

I actually install fire alarm equipment for a living, and this is what I have in my house.

You can get wireless interlinked ones, but they're not cheap.
