I haven't see HU so take that out of the equation for everything else. My opinions would be:
Fate/Zero and FMAB have the best animation combined with the least amount of cheap tactics. I don't think it's even a subjective argument with the other stuff on the list. Death Note has the best music by a long shot. I think SG has the best characters although it's neck and neck with DN and FZ. FMAB and SG have the best premise imo. For story... I assuming that with that being separate from premise and characters we're talking about plot points and execution, I would go for SG in a tie with FZ. DN and FMAB had some great stuff but they go off the rails and get pretty meh at points while for me SG and FZ for the most part started good and then got better and better and better.
My vote... there are episodes of FMAB and DN that I'd rather watch more than any episode of the others but when taking it as a whole, I'd go for either FZ or SG. FZ gets my vote. I'm a sucker for a time travel story and I love where SG eventually goes but I remember watching about half of the first half of the series wondering when they'd ever get around to something that felt like we were finally on the path to the dead Kurisu we saw in episode one. Once it picks up I think it tops FZ at it's best but FZ didn't have any episodes where I felt like the series would be better if they got rid of like 4-6 episodes.
