Chrome lined barrels aren't necessarily better than non-chrome lined barrels, but they aren't necessarily worse either.
They do tend to last longer than a stainless steel or chrome-moly barrel. They can be less accurate, not necessarily because the chrome lining cannot be evenly applied (that has a smidgen to do with it though), but because over time especially in rifles that are fired for accuracy using warm(er) loads than average (most common in the NRA high power crowd), the chrome lining in the throat may start to pit and flake away which will definitely throw accuracy in the toilet.
In general for most folks out there, chrome lined barrels are just fine. For match shooters, and from companies that make premium barrels targeted at match shooters, it's usually non-chrome lined, in stainless or chrome moly.
