are you asking about a difference in thread quality or kind?? there is definitely a difference both ways. i took a "thread" class and couldn't believe what a difference using the right thread makes.
differences include the kind of twist - which determines how you set it on the machine - horizontal or vertical. - also the material the thread is made of - cotton, synthetic, etc. I don't know this stuff by memory yet or could be more helpful but you could google thread and see if you get any help there.
