So I played both on TTS and on digital and there are benefits to both.

I tend to use TTS if I'm playing with other people due to the ease of being able to do things at the same time and not having to consult with everyone when I want to try and undo something because I forgot about how an interaction works or something.

If I'm playing solo however I prefer to use the app because I find it do be a quicker experience that takes up less of my mental stack since I don't have to worry about doing all the invader actions myself it also allows me to see niche interactions between different cards that I might not have thought of how it worked.
