I'm curious about whether fleet gear is better than omega gear... can anyone tell me which is better?

At this point you can only get Fleet weapons since the [Borg] weapons were removed since they did not even fully worked and they taken 2 mods anyways (glorified blues), STFs Sets are still the best.

It depends on what you're looking at. The Omega gear has item sets, which are in general more powerful than non-set items. However, its selection is rather limited to mostly Borg-derived and anti-Borg equipment. Except for the item sets, if you're not fighting Borg day in and day out, you're better off with Fleet gear.

As far as I know, though, the MACO shield is still the best in the game.

Stick with the fleet gear! It's better and cheaper!

No, its not.

Weapons, yes but that is because STFs weapons were removed but sets? no way in hell. And you be paying its weight in Dilithium anyway so why waste it in Ship equipment when it not going to beat the sets.

Ground is even more lopsided since sets give powers, like MACO that comes with a buildin shield recharger so if you are not playing a Eng you get a Shield recharging ability for free, not even mentioning the passive abilities that Fleet Ground gear will lack.

Outside Ship weapons, you go with the Omega Store if you can.

I love my fleet weapons tbh <3

Unbalanced set bonuses and gear are a crutch.

Stick with fleet gear. Besides, the loss of space set bonuses are no big deal unless you favor the full borg set in which case see the above statement.
