I've got fleet gear and set gear, the fleet gear might have better numbers but doesn't hold anything up to the massive dodge bonus the omega set gives you, marginally better shields compared to 100+ dodge? No thanks. Even the maco shield set gives you a shield heal and will out perform the basic fleet gear.
It doesn't take a month on Defera to get a Fractal remodulator... My entire bridge crew has them. The fractal remodulator feels much faster than the standard, but once you go to the set one you won't want to go back.
