Simpler is definitely easier... it took me a few solid days of pounding away on twine, sugarcube's documentation and Google to get what I think is a good template that I like. And even then I find I go back to tweak or change something I'm not happy with. There is definitely more coding than in harlowe, although once you figure out what you are trying to do it's easy to make it quickly repeatable.
Definitely stick with what you know and are comfortable using! That keeps the story coming and holds off the riots for falling behind. It's a significant effort to convert from one format to the other mid-stream, and then having to get up to speed on how to use it. If you wanted to see how I've been able to tweak mine, I can send the project, for purely research purposes of course.
By all means feel free to reach out! I've definitely gotten my feet wet with both formats now and enjoying it more than I had thought I would.
