Out of the three, there's only the FDS I haven't tried at all. I like the look of the FGS, but since I'm not a dedicated pew pew player, it fell into the slow, tanky and useless bracket.
The FAS I liked... certainly no multirole and nowt nearly as good as a Python for that purpose, but then again...I already had the FDL for pew pew, so it fell into just 'flying something that did things slightly less efficiently than the Ferdie' bracket. Hated the hardpopint placement too... Fun, but superceded.
Looks wise, the FAS/FDS should have
Tefal or
Morphy-Richards written on the side of them. I'll need to try the FDS at some point, but having the permanent Python in the garage makes it merely a pointless addition.
Regarding all of that blurb I just wrote... the Federal ships have something for everyone getting to the Python/Anaconda stage of playing... once you have one or both of those, apart from the drop ship, they're merely toys... like the Ferdie... when you're not doing important stuff like playing the majority of the game that exists outside of a res site.
The FDS looks more useful for multirole, you can mine/trade/smuggle quite happily in it... recommended out of the three for that reason
. Sorry I laugh at the last one because I personally think the jump range on any of the three is not that great. But in all seriousness the best multi role.
