After using LEDs, I find nothing really comes close to metal halides. Especially if you are 90% SPS.
The growth of your SPS will be a lot better under the halides.
I have run both and do not find there to be a significant difference, unless you are having to deal with the spread/shading issues, YMMV. My approach to running LEDs has been different from most of the advice given on how to properly run them. I should have cooked/fried everything in my tank based on most of the common recommendation. Proper operation is a big variable that can be troublesome.
