I'd say the scent is very similar to Pampers' scent (which is baby powderish, at least IMO). It doesn't smell exactly like baby powder, but it's close to it or at least that's "part" of the scent. Either way, I like the scent and always get the scented ones.
I have (I think) about a 32"-36" waist. I ordered a sample pack of one medium and one large. The large felt a little big, but it still fit and I had no leaks. The medium fit wonderfully and I also experienced no leaks with it either. I'd say it's sized a little bigger than Abenas (my M4s feel much more snug at least, but as you mentioned this could have to do with how well it's taped on). So I'd say the mediums would probably fit you best, but if you prefer a bigger/looser fit or your body dimensions are different you could totally get and pull off a large.
The ABU Space is my #1 favorite diaper right now with Abenas coming in at second (they use to be my #1) if price isn't taken into consideration. I really wanna try the Little Paws though. I like their designs more than the Space, although I like the Space design as well, so if they fit and function like the Space (which they should) then they'll probably be my new #1s.
