I think (correct me if I am wrong) the T9 edges it if you want to carry a shield however.nope - a Cutter hauls 794 to perload on optimized role, a T9 788 to, so the Cutter hauls more.
Nevertheless I prefer the T9 over the Cutter as I cannot tand that ships drifting, especcially with Grade 5 dirty drives it a pain in the bum
I admit however it's been a long time since I flew one as still not got the rank (so it was back when it was in beta)
for me however the cutter just didn't look utilitarian enough for me to use as a bulk trader , where as the T9 just seemed right to me which is why I never bothered deliberately getting the rank for it.
