Elegoo Mars 2 Pro Vs Anycubic Photon Mono 4k

so does anyone her have both google home and alexa at home? do you use both or only one of them. Here is my thought, I have a few chromecast audio in bed rooms, but I want to add voice command to those room without having to scream for my main/only google home to hear me. Is it worth it to spend $35 for the dots since I have the Chromcast audios already set up, so I can use as both speaker and voice control? Or am I better saving up to add GHs to those rooms?
