Raven. For starters, the idea that Neo was conifdent in taking on half-maiden Cinder was primarly because Cinder for the most part, was completely caught off guard and wasn't fighting seriously but trying to talk her out of it (and that's if you don't consider her probably not being at 100% after the cave in, being frozen, etc. but assuming she is...). By the time she activated her power, Neo froze in place and it was clear she would've been stomped. In comparison, Raven is far more experinced than Cinder or Neo (heck, her entire fight with Cinder had Raven playing a strong offense game for the most part, only really getting caught offguard by Cinder's Grimm arm - which was clearly draining her aura or Maiden powers). Also, Raven's portals would easily allow her to get the drop if needbe, and to turn into a raven would allow her to stay mobile, especially to (again) get the drop should Neo try her "now you see me" tactics. Or just flat out dice her up.
Add in that the fact Neo's first sighting of Raven canonically was to GTFO despite losing no stamina whatsoever against Yang, I don't see the result changing for base Raven winning unless Neo starts manhandling Qrow at full strength (which I won't be surprised happens in the future)
