I think I would prefer Discord over texting, but I do too admire texting for easy communication. Though I've had multiple people not return my texts, and that always tends to bother me.
I don't do the normal text message thing all the time. It's a boring way of conversation. I do it once in a while or when I don't want to have a long chat with the person that I'm texting.
If I am chatting on Discord I do prefer texting. But in real life scenarios, I like to call majority of the time. My rule of thumb has always been if it's short and sweet - text. If it is a length conversation then I would prefer to call and get it over with instead of sending texts back and forth.
I only text when what I have to say something that is a bit confidential. I prefer calling generally. That is because when I call, there is a chance that you feel the emotions of the conversation from my voice.
