ed: most people like muv-luv alternative, but you have to get through the considerably less well-received extra and unlimited to reach it (as i'm sure you know). i thought extra was downright terrible, but your mileage may vary - you're probably more tolerant of inane slice of life than i am. i would suggest looking at screenshots before trying it because the art is hilariously bad.
now i wasn't a fan of alternative either, but i'm nearly alone in that so i won't go into detail about my opinion there. though keep in mind (this is more universal) that it's really, really long and doesn't pick up for a while. on the upside, it's the highest-rated game on vndb by a wide margin, for whatever that's worth. i keep telling newbie to read it so i have another opinion but he's too busy reading japanese-only vns and informing us all of how very great and japanese they are.
i think you've already read most of what i consider good, so i don't really have other suggestions. if we're talking about navel, i very much want oretsuba to get translated, but it's extremely long and difficult. don't have high hopes (there were some rumors that it was being negotiated for a while back, but i haven't heard anything on the subject since)
