Red Sea Coral Salt Mix vs. Instant Ocean Reef Crystals

[ClownieTang]

for a 130g reef tank with sps, lps, soft coral, and anemones. I will be dosing calcium/alk, iodide, magnesium, and trace elements, if needed. I will be testing for all of them. -will be mixing salt mixes with RO/DI water from my own filter.
Which salt mix is better for my reef? which is better overall? Red Sea vs. Reef Crystals
