The challenge with Linear parts is finding a way to justify using a $3 regulator IC when a $1 part seems to be available elsewhere. Clearly, performance alone can sometimes be a decider, but a good design doesn't rely on having precise power supplies.
Parts count is also a problem, Linear are very flexible but often need more support parts.
That said, Linear are such nice people to deal with, I always go there first with a new design just in case their solution does turn out to be a winner!
