Lighting for my frag tsnk. T5 or MH

hi, i was wondering which type of lighting would contribute to better growth in corals, t5 or mh, in a 10 gallon tank. it would either be a 4 bulb t5 fixture or 70 watt MH fixture. any suggestions would help
 
im thinking of going with 2 10000k's and 2 actinic then when i replace go with 1 14000, 1 10000, and 2 actinics to see what i like better. thanks guys
