If you take care of your rifle as you say you do there is nothing wrong with Blue. A stainless gun will rust so they also need to be taken care of.
And yes XS is Short action and XL is long action. But till Marlin gets there barrels right again I would stay away from the XS line. But the XL line at this point is still a good rifle for the money spent.
