All things being equal, I'd go with the Linhof if I had the $$ to spare. Other than both cameras are hand holdable, I feel there simply is no comparison----the Linhof will give you "more" (albeit at a price, especially in terms of wieght and complexity) That said, the Crown is a superb camera for what it is, and a real bargain in my book. Both will serve as a learning platform and both can (have) been used to take very exceptional photographs.
Since you want to explore lf, I'd go with the Linhof and it's additional movements, however if you want a 4x5 point and shoot, the Crown will do everything you'll ask of it, for far less expense and wieght than the Linhof.
