What smart remote specifications matter most?

As a very rough rule of thumb, the main purpose of the remote control’s specifications sheet is to bombard you with confusing terms and display panels.

Rather than count on the specification sheet to provide details on which smart remote will perform better than another, our suggestion is to ignore it. The sheet can help when trying to differentiate a remote based on features, some care about whether it supports WiFi, IR, and Bluetooth. What’s more， support voice control by Amazon Alexa or Google Assistant or not； It can access your home automation system or not？ It is compatible with all devices like TVs， Amplifiers， DVDs， air conditioners， gamers， Projector, and anything you want or not. So what is your opinion？
