Streets of Edo
Man, it's striking how different the taste is on ffnet vs on AO3 for readers of my fics
Streets of Edo
(and I'm aware it's a bit pathetic to go on about fic stats when you post new fics as rarely as I do)
Streets of Edo
but anyway, my top fics on ffnet in terms of readers' favourites: Opening the Box, Absence, Bringing Him In, Tow Line, and A Quiet Walk in the Noonday Heat
Streets of Edo
that is to say, Sanji + Usopp gen angst, Strawhats ensemble gen angst, Strawhats ensemble hurt/comfort I guess it is, Zoro + Usopp hurt/comfort (maybe mildly shippy, maybe not) and Zoro character exploration
Streets of Edo
gen fic
Streets of Edo
not a shippy one in the lot (not even het, I'll note)
Streets of Edo
top five fics on AO3 in terms of kudos by readers: Caught in the Rain, I Get Ideas, Nervously, Tub and Bucket, and Towards the Shores of Sleep
Streets of Edo
that is to say, Sanji/Usopp get-together shipfic, collection of short stories focused on Strawhat pairings, very short Usopp/Zoro fic, somewhat longer Zosopp, and mildly shippy h/c Sanji/Usopp.
Streets of Edo
and if the collection doesn't count, the next one is Tell Me This, a Zosopp fic that's all about Zoro and Usopp talking to other crewmates about their relationship.
Streets of Edo
definite trends here in both cases. 
Streets of Edo
...and my most popular shipfic is het, Franky/Robin
