In some ways. Verticles can sort-of be analogized to individual node.js processes. The underlying service bus, however, is tremendously helpful and well-designed and, IMO, the real reason to use it.

The choices for me for my current project were vert.x or Dropwizard; I went with Dropwizard for now for ease of early development, but I've structured it so that I could fairly easily convert my Jersey resources (structured themselves as completely separate modules inside a monolithic application) into vert.x verticles.
