Texting. I've never been a big phone person so I love being able to text. Especially my mom who has no attention span. If I tell her something on the phone, I know she was probably distracted and didn't hear me. If its important, I text her so I know she saw the words and will therefore remember!
I kinda hate both, I hate having a cell phone at all but DH made me get one. I usually just text them.
