Best RPG-esque Modpack with Iron's Spells?

Hi there guys, I am brand new here so please be gentle. But I was hoping to poll the court of public opinion on what RPG style modlists that have Iron's spells y'all think are the most fun?

I recently tried out dawncraft some, and kind of bounced off it. But I don't really know where else to look, so I'd love to hear from y'all.
