JHK,
What is more enriching is to have face-to-face conversation or even interactive phone conversations. To notice body language, vocal inflections and tonal quality and other cues you can get from these communication modalities give you more information about each other than words on a screen.
Frankly I find having any kind of meaningful conversation as tedious to do over texting.
I assume that these questions are not theoretical but specifically about communication with one particular person. If that is the case then best to ask that person directly for each of us are different in our communication styles and preferences.
Dull and boring are subjective. Enriching is subject to interpretation.
