Digital vs. Paper?

Hello! I am new to these patterns as I have new girl (and boy) grandbabies (twins!). They are now toddlers actually and I want to do some sewing for them. I have long admired these oliver & s patterns online and have a ? before I order. I am a digital person, but I wanted advice on how to decide which to buy, digital or paper? What are the pros/cons of each format? Thanks so much!
