MaxSpect R420R or AI Hydra 52?

[Tiansho]

So after some time at looking at these two units for my 80 Gal upgrade, I thought to come to the forum and ask for input/opinions on what should I do for my tank.

I currently upgraded to an 80 Gal tank from a 40 Gal. Over my 40 Gal I had a MaxSpect R420R 120 W 10,000K. It was good for my Lps dominated tank with one sps . Now in my new tank, I want to keep the LPS I have, but I want to add more SPS.

LPS: Bubble tip, Mushrooms, Hammer Head, green zoas, and GSP.
SPS: Red Planet

I know I need to add a light, and was looking to buy another R420R 150W and get it done with, but the AI hydra seems like a great choice as well.

I currently live in an apartment, and when I move to a house I will upgrade, Don't know time frame yet. the only sure thing is I will upgrade to a >160 G !!!!

for that size a tank I will have to get more lights. Should I start transitioning to the hydras or stay with MaxSpect? any input on these lights or other brands for that matter is appreciated.

I know another R420R 150W would be around $600 and the AI about $900. big price difference.

Thank you.
