TextStream Object

I just started learning about the FileSystemObject and have a few questions.
What is the difference between using the FSO createtextfile and the Output method or the opentextfile and the Input method, I mean why use one over the other. eg

PHP Code:

---

    dim OStream as TextStream
    set OStream=fso.CreateTextFile("c:\testFile.txt",true,false)
    OStream.WriteLine text1
   
or
  
   file=freefile
   strFile = "c:\testFile2.txt"
    Open strFile For Output As #File
        Print #File, text1
    Close #File 


---

Just curious.

this is OLD VB

Code:

---

file=freefile
  strFile = "c:\testFile2.txt"
    Open strFile For Output As #File
        Print #File, text1
    Close #File

---

Now this takes advantage of MS COM component thus being faster and efficient!

Code:

---

dim OStream as TextStream
    set OStream=fso.CreateTextFile("c:\testFile.txt",true,false)
    OStream.WriteLine text1
