The advantages of a 532 are the good beam quality and the slightly higher luminous efficiency. 520 is a prettier color though IMO
If it is not an urgent need--wait a little bit and save up the extra dollars needed to go with best quality--then you don't have to buy another unit to upgrade the quality and/or features.
