Question about route types

Hello,

I was wondering when I am selecting route types on the app (Paved, Gravel, Any, Cycle Routes) I got confused. Initially I guessed that the app by default would take me via a quiet route prioritising cycleways in London, but having found the route type feature I would like some clarification. Would the quietest road, and the most cycle friendly (in theory) be the 'cycle routes'?

e.g from caledonian park to charing cross hospital I get starkly different routes when switching between these modes/

Thank you very much!
