The LM317 is limited to 1.5A. The L200 can output up to 2A.
The LM317 has better line and load regulating characteristics, and a lower dropout voltage (1.7 vs the L200's 2V).

At 0.5A output, the L200 regulates to 1.4% typical; no maximum provided.
The LM317 is 0.3% typical over the full operating range (temp and current).
