Yes there is. Lucky you can only use a starnut and The only come in 10 mm off set. Vertx has a threaded insert that works like a starnut and way easier. they can be used with a starnut as well. They come in 10mm and zero off set. As in looks they are basically the same.
Vertx SMX forks aren't CNC'd wrong. If you notice on the Lucky, one side is CNC'd bigger than the other. Vertx SMX's are also better because they have an intergrated starnut, come in different colors, come in zero offset, and cheaper.
So yeah, Vertx is much better.
