Kenmo, I took a look at the Rocket3F Youtube videos, and honestly, it looks to me like a slightly more polished and advanced iteration of the same software. I can not speak for the developers obviously, and I'm not criticizing it at all. It actually looks like a very decent piece of software from the videos, especially for beginner level or intermediate modelers. Just speaking from a personal observation perspective alone, it seems the main difference is R3F has more industry standard and intuitive UI.
