macro lens- you have to focus from a distance.
extension tube- you have to focus very close to the subject. you have to be so close to the object that you can kiss it. have to attach to lens.

i also think that
macro lens- can magnify only to a certain extent.
extension tube- can magnify things to a more extreme level.

however, if you combine both the macro lens and the extension tubes i think you will have a very powerful combo!!!!

with extension tube, you cannot get infinity focus
if you use 25mm extension for a 50mm lens, you can't focus farther than 10m
