Yes, in my opinion, it is worth it. And the feature, which accomplishes this is the extremely small chamber. Look at the picture below. The build deck in front fits into the chamber with chimney. As you can see, not much space. If you do not fasten the post screws, it touches the top of the chamber and cause a short. Most effective vaporization ever.

This is not a high wattage tank, the wick will not be able to keep up, but at between 10 and 12.5 Watts I get the same, if cooler and more flavourful, vape from it than from a Chalice III at around 23 W - the same juice. And the vapour is at least double in volume and of a much finer texture. Many vape at around 20W on the GEM. One or two GEM owners have enlarged the wicking holes slightly.
Next I need to try TC vaping with this combination:
