Eh, I don't think Griffons are that much bigger, but this isn't a question of which scythe is better or which scythe-wielder is stronger (Naturally, an adult is going to be stronger than a child and able to do more). The real question is which weapon "wow'd" people when they were first introduced, and I can safely assume that Crescent Rose wow'd us all in the Red Trailer, right? Because we hadn't seen anything like that before (at least I hadn't). From the audience's perspective, since we're so familiar with Crescent Rose by now, Qrow's scythe would need to make a huge positive first impression in order to wow fans because we're used to seeing what a scythe can do. When the time came for Qrow to use his scythe form, we were already a little desensitized, so Qrow needed to really up the ante in order to wow audiences, something that would have been more possible during his fight with Winter so that we saw every aspect of his weapon instead of only a small part of it. I felt that the reveal of Qrow's weapon in this fight was more of a "wow" moment than when we actually saw his scythe for the first time later in the volume, and the fact that we didn't see it during the Winter fight actually helped contribute to the ultimate reveal being so underwhelming because of how little it was actually used up to that point. The scythe felt more like an add-on to Qrow's weapon rather than being his true weapon. It felt like, "Qrow has this really cool sword/shotgun combo with gears inside the blade to give it this cool mysterious look.....Oh, and it's a scythe too. Did I forget to mention that?" That's what made it feel underwhelming to me. We were told since the very beginning that Qrow was a proficient scythe wielder, and everything in the first two Volumes alluded to it well. Then when we actually meet Qrow, he doesn't use the scythe against Winter, and doesn't use it for the majority of the Volume until the very, very last minute and only to perform one kill. This build up to nothing is very similar to all the hype that was generated for team CFVY, only to get a lackluster into of them just walking by, and then only seeing them fight in the fiasco that is the Volume II finale. Sure, the wonky animation made it look worse and didn't do the moment any favors, but it's really the build up to nothing that truly makes it underwhelming. When that one kill was done, all I found myself asking was, "Is that it? Okay then. Moving on."
