It depends on your criteria. Chrome lining is very difficult to apply in a even coating. Which means it decreases accuracy. The typical proccess leaves high and low spots in the bore and distorts bullet flight. While its actually a very desirable thing for belt fed machine guns as they are more area effect weapons its not for the average soldier's rifle.
Think about it like running an indy car over a dirt road that has seen several seasons of rainstorms with no upkeep to running the same car on a track designed and maintaned for racing purposes.
It offers some advantages in that its very difficult for the heat and pressure of a fired round to eat it away so you get greatly increased barrel life.
In terms of using surplus russian ammo shellac preservative coatings will not stick or transfer itself to chrome lined metal. Chrome is also extremely rust resistant so corrosive primers have nearly zero effect on chromed chambers and bores.
Modern ar15 barrels by some barrel makers have nearly perfected chrome lining techniques and in the higher end ar15 market you get nearly no accuracy loss and all the benefits.
