My tank is 36"X18"X18" and am running Coralife 36" 2X96W bulbs the T5 fixture would be better?

Basically what it comes down to is whether or not T5s would be best suited to your aquarium system. There are many threads on RC with actual data comparing metal halide setups to T5 setups and most of the time PAR readings are fairly similar with metal halides typically producing slightly more PAR than T5s. Depending on the bulbs, ballasts, and reflectors used, either metal halide or T5s can produce more PAR so it really depends on the equipment used as well. With T5s, you do have a more customizable light spectrum though as there are many different bulbs you can choose from.
I'm sure that you would be more than happy after making the switch from PC to T5's. Just make sure the T5s are High Output (HO) and not normal output (NO). As you said, individual reflectors as well as high quality bulbs such as aquascience, ATI, KZ, giesmann, etc will make a huge difference in performance.
