Does dry cleaning get clothes as clean as soap and water?

There are obviously some items which are dry clean only. I can think of men’s suits, for example. Let’s leave those out of this discussion.

I have some nice shirts that give instructions for washing, and then they add “dry cleaning recommended.” It seems almost instinctual that washing with soap and water would render a cleaner garment. Does it?

I also have some linen shirts that give washing instructions while other linen shirts demand dry cleaning. Why is there a difference?

Do some fabrics wear better from washing while others from dry cleaning?
