I much prefer to call. I forget what the stat is, but it is something like only 10% of all communication is the actual words that we are saying. The rest is tone, eye contact, body language, etc. So in know you don't get all of that in calling, but it is way better than texting. I hate misinterpreting texts. I have done it so many times in my life and some relationships have gone through rough times because of it.
However, I acknowledge that texting is cheeper and more efficient for quick reminders/letting-you-knows. I text much more than I call and Skype/the forum have taught me to communicate better through typing/texting. But I think I will always prefer the more human type contact.
