I'm not sure if you noticed this or not, but you mentioned the Raptor 90. The newest Raptor 90 and newest Outlaw 110 EFI are based on the same quad. If you look closely at the frame, brakes, engine, suspension, etc and even the name stamped on the engine you'll see they're the same except for what you mentioned, being a horn, EFI, brake light, headlights (sort of) more ccs, and different looks.
I lean toward the Outlaw 110 myself. One plus I see to the Raptor 90 is the back up kick start and it being less reliant on a battery than the EFI. Otherwise, I think the advantage goes to the Outlaw for additional features.
