Personally, I like both. It's 8pts and I shy away from Gunnery Teams on an ISD-I anyway, because you won't often get two ships in Close Range at the same time.
Oh, and I think I mentioned this earlier, ships that throw lots of Reds will love Sensor Teams and/or H9s if flotillas really explode.
Agreed. Its a personal preference, though. For me LS together with OE feels like overinsuring, but that may be different for different fleets.
I can see the usage of Sensor teams/H9s expanding, however Sensor team ship for me is the one that throws red dices and can't (or doesn't want to) take H9's. And H9 is for everyone else.
