For your first question its like asking samsung or iphone. This is one of the biggest debates of the hobby, if the option was mine I would run a hybrid of t5s and leds. As far as I am concerned both work and results speak for their selves, what ever you go with at the end should work.
cant help you in the second question sorry.
