I had T5s, since replaced with LED Lighting. Simply put you can get very good light from T5s. I used a mix of 10000K bulbs and actinic bulbs in a 1 to 1 ratio.
That being said, the only big advantage you get out of T5 verses LED is lower initial purchase price. Once you figure the TCO (Total Cost of Ownership) over 5 years, the LEDs beat the T5s hands down. You will have no bulb replacement costs, lower power consumption, and much better control with LEDs.
As you can see, I liked them for awhile, but they were replaced with something I consider much better.
Perhaps the questions should be is why don't you like LED lighting.
