I like them, but they should be reasonable.
UC Gundam is pretty good with this but for a more recent example gwitch manages to be on both ends of the spectrum
The Daribalde's funnels are great.
It has defensive bits that are flying armor plates, and offensive bits that are flying beam sabers which can additionally be mounted as forearms.
They're simple and with a clear purpose.
And on the other hand, Aerial's bits are busted.
They have the gwitch equivalent of I fields, just float around instead of having visible thrusters, spam beams like crazy, are wifi extenders, and improve the Aerial's performance when docked because of course they do.
These things just do everything, and they end up incredibly boring as a result.
