Which country are you in? The models vary somewhat by region.
If you are in the US, the newest models are the
V3 2018 hub, model IM6001-V3
And the SmartThings WiFi with Plume WiFi Mesh Router, model ET-WV525 (This replaced the “Samsung Connect Home” model in the US. You can tell the difference because the new model has two logos on top, Samsung and SmartThings. The discontinued model just said Samsung.)
They are equal as far as zigbee/zwave but the IM6001-V3 gets more frequent updates because the ET-WV525 has to coordinate its updates with the Plume team, who are a different company.
(There is also an ADT model, but it’s been unofficially discontinued. Very difficult to get devices or support for it.)
My personal recommendation for the US is just to get the IM6001-V3 and get a different brand of WiFi mesh router if you want one. The Samsung model lacks a lot of admin tools and doesn’t have any particular advantages other than one less physical box. It’s not a bad WiFi mesh router, just not quite as good as some of the competition. JMO, obviously.
