Different folks, different strokes. Here's my take on things.
Habaki or non-habaki? Taken by itself, it really doesn't matter to me. I think non-habaki looks a bit nicer. My users do not look nice. My #1 star, the BGRS villager, is downright ugly at this point. It's got patina, scuffs, black rust and a nearly permanent coating of cured pine sap on it. When the sap gets too sticky for my liking I rub it down with dirt. When I have the time, it gets scrubbed with a green scrubby pad and hot water. If I'm out in the woods, water and sand suffice and whatever's left gets wiped off on a pants leg. The wood looks like hell and the steel fittings are beginning to rust. However, it's handy and it holds an edge like nobody's business, and these things are important to me. That, and it's mine, and it looks like it's mine.
Brass? Steel? Doesn't matter. Brass turns green, steel turns red/black. I could care less. Brass probably handles the rain a bit better so that's fine for me.
Cho creep? I'll accept that it's less appealing visually than no creep but I haven't noticed a difference in handling. Like some of the others have said, though...might as well move the cho back and put some more usable edge on the thing, or move it the other way and give us some more handle to hold on to. Either one works for me.
Handle size? I've never had a problem with them being too large. I have had problems with them being too small, and like Nasty said it's a lot easier to subtract wood than to add it. I'd rather that they were too big. Straight or curved? I've got a preference for curved but there's nothing wrong with straight. A well-shaped straight handle is preferable by far to a poorly-shaped curved one. It's a variable, but a small one in the overall picture for me.
Scabbards? I've got loose scabbards, tight scabbards, and a couple of scabbards that're nearly perfect. Loose ones are easy to fix: glue in a shim, or (if you want a better fit to the blade itself) soak that sucker in water and wrap it in some surgical tubing, then let it dry. Tight ones, I haven't had so much luck with. I'd rather that they erred on the loose side simply because it's easier for me to correct. How tight is tight enough? I'm not a martial artist and I don't intend to use my khuks on living things. (I actually find the idea a bit ridiculous, given my particular circumstances.) I don't care if my draw is a bit slow. I do
not want one of them leaving its scabbard unless I draw it, however - this is not negotiable. (Same rule for firearms - I always opt for more retention, not less.) I climb hills, crawl through brush, enter and exit vehicles, and occasionally run with a khuk hanging on my belt. It
must stay in its scabbard while I'm doing this. I should be able to hold the scabbard upside down and shake it and the khuk should not move; if it passes this test, and I can still draw it without pulling any muscles, it's good. This can be done with most scabbards but it can take a while to fine tune everything. If we're talking about a khuk that gets used frequently, it's worth the effort.
Of course, these are just my opinions. They're only correct if you agree with them.
