The “clickyness” of all these switches feels about the same to me.
The GE switches have a slightly heftier/louder relay sound. Not sure what that means in reliability between the three. Only time will tell.
The inovelli switches have a slightly different white tone to their white color and don’t quite match the other switches or switch covers.
The inovelli led on the switch is a very dim blue compared to the others. That can be good in a bedroom at night. The other switches are kind of too bright for those who like it dark in the room. But that makes them not look well next to another brand. The homeseer 100 series are white LEDs and very bright (with one of these in a bathroom you don’t need a night light). The 200 series are color changeable.
I think that’s it. I used the homeseer switches for all my three way as I don’t like the idea of using a normal toggle switch for the slave (I want the same click action and scene functions). I have homeseer dimmers in all the bathroom vanities and in the main living room. I put the GE on all my exhaust fans and closet lights because they have very basic features and won’t need anything else for a fan (bought them on sale when cheaper than the others). The rest are inovelli scene switches because they have the most features of any other switch on the market right now. Their ability to disable the relay so I can use smart bulbs is a god send.
Oh and on reliability. GE have been solid and I have had some of them the longest. Homeseer were the next brand I invested in and I have already had to replace a failed dimmer and one of their switches locked up and had to be power cycled at the breaker. The inovelli I have had installed for only about a week with the exception of one switch I bought and installed last year. No issues with them yet.
