“Best” remains subjective. Based on their published videos, The new Homeseer switches have a very audible click which might bother some people.
Also, they only come in white.
More importantly, the new Homeseer line uses the “central scene command” which SmartThings does not include support for. They can probably still be made to work, but someone is going to have to write a custom device handler for them.
They are certainly promising devices, but until some community members actually have them working, I don’t think we can label them “best” yet.
