Depends on the situation. I don't mind calling, usually, things are solved faster that way. But if I need to agree on something important, I like to have an email conversation, as I can always get back and check all the details. What about you?
I prefer texting. I am more introverted than extroverted. Talking and calling is not a thing I enjoy doing sometimes. But it depends on a couple of factors. Such as who I am talking with and whether I am in a good mode or not!
Depends on the circumstances and the person I'm communicating with. As per my professional experience, certain folks in senior management tend to be very busy and most likely receive a barrage of messages - so quite often they may unintentionally overlook your message - so its always safer to call the person, if he/she has not responded.
In personal life, among friends and family the approach is very different
