Z-wave is far, far more reliable than Insteon, which is why I'm moving in that direction and Insteon command modules have to be directly on power and thus power issues cause reliability issues.
I'd avoid Z-wave these days unless you have immediate need. AFAIK the aim of Thread/Matter is going to be deprecating it and everyone will move over to that. It'll take a bit of time of course, for existing/future products to be migrated over, but I feel Z-wave and Zigbee are the past, and shortly to become relatively completely deprecated for new devices.
 
I think it depends on the system used, protocol, and device support.

Mine was relatively easy, but I'm using several commercial products and integrating Z-Wave, Insteon, HomeKit, Davis Weather Station with plug-ins (typically FOSS) and for the most part it has just worked. Only Nanoleaf has given me issues (well, Siri <-> Apple Home has issues on HomePods intermittently for no apparent reason). Z-wave is far, far more reliable than Insteon, which is why I'm moving in that direction and Insteon command modules have to be directly on power and thus power issues cause reliability issues.

FOSS has several advantages - mainly you have more troubleshooting ability, more flexibility and you will never be locked out of your devices. I'm not going to say cost, because it typically costs more in time. My HA system started in 1997! and has just evolved over time.
Yeah I do appreciate there's more than some purchasing bias when I made the statement about zigbee2mqtt. Just as a point of philosophy I want to self-host but am also keen not to leak anything more to our cloud overlords not least because they don't need to know any more about my life than they do but also the track record of sunsetting services. I'm also not all that ambitious about my automation (well not yet anyway). Hence the gushing about z2m rather than the glue that HA/OHAB/the rest have in addition or on top; granted zigbee isn't exactly linux device drivers but the openness and speed of adoption of new devices is great to see.

Nah, if they take off it’ll integrate in to the controller and you can switch devices as they fail. Nice thing about the major HA controllers is they don’t care what protocols they are talking, it is just another plugin.

Fully agree here, other than HomeKit (which is really a minor part of my setup), it's all hosted on a local server with no data in cloud.
