Alright, here's my perspective on things:

To me, landlubber seems almost certainly town, which I suspect is not a particularly controversial sentiment. However, after him I'd consider GH to be the least scummy. I feel like his PMing Visorslash doesn't really tell us anything about his alignment, but his posts since make me think he is town, and I don't find his townie explanation for the message to be particularly implausible.

Of the remainder, I've done a complete 180 with respect to Winston since D1 - he's giving me similar vibes of townie analysis to landlubber. jht, I...have absolutely nothing on. Montmorency feels a little off to me, but I acknowledge that I might be a little biased here due to his attack on me. Finally, 'khaan, who I've been at least a little suspicious of for the whole game, and who I probably would have ended up voting for today. Unfortunately he had to go and post a highly convincing argument against Winston that was nearly enough to change my mind on him, and at any rate lowered 'khaan on my mafia scale a bit.

tl;dr: Montmorency and sereikhaan are the two people I find individually most suspicious (with jht taking third essentially by default).

vote: Montmorency

Partly because he's the most scummy of the contenders, and partly because I want to see how the votes move in a tiebreaker round.
