why THF and dioxane are strong lewis base and on the other hand propyl ether and isopropyl ether and ethyl ether are weak lewis base?

in THF and Dioxane the oxygen is exposed the alkyl groups are looking to the back because of the ring

in diethylether the alkyl-groups can cover up the oxygen better
