Spen And Apple Pencil

I haveSamsung Note5 and iPad Pro 9.7.Both of them can use pens but their pens have many differences.The Note5 supports the Spen, you can easily take notes ,do simple sketches or quickly get a screenshot ,note on it and send it to others.It's very useful for work.The Apple Pencil is another kind of digital stylus pens.It is more like a real pencil.You can not do the efficient things like Spen.But it is an amazing tool for paintings.Its feel is similar with the a pen.You can make different effects with different angles.Those features can let me  paint freely on my iPad.These two digital stylus pens is for different using fields.They are both good tools in their own fields.
