The advantage you get with charges on a hitbox is also there for QCFs/QCBs and DPs. I'd argue it's a bigger advantage for command inputs then charges. I used one briefly back in the UMVC3 days to spam fly cancel fireballs with Morrigan.Hitbox is so good for charging that SF6 made it illegal for a leverless controller to output Down+Up as Up in Capcom pro tour tournaments
