I don't think this really worth the price to me even though I regularly do freelance work using Dragonframe, but it might be worth it to you if you really need full control with one simple keypad. But this is also just a quality of life upgrade and might not be worth the $100 price tag. Being able to control the whole program with one controller rather then having to bring in a mouse would be great. As my sets are on a stand up work place and across the room from my computer (which is not easily movable) and is a sitting work-space, having to deal with a mouse & keyboard in addition to the controller can be annoying, particularly setting up shots in the Cinematography mode. The first is full control of Dragonframe with only the controller. I have looked through the update to see what Dragonframe 4 brings to the table and there are two things that stand out to me. Why should you upgrade if you already have v3.x? Now I don't know this for sure but the the Bluetooth controller (which you can purchase as a stand alone) should work with older versions of Dragonframe and could be a huge quality of life upgrade for some people. However, if your like me and have been using Dragonframe 3 for a while the upgrade cost is $95 or $125 with Bluetooth controller.

So if you have been thinking of upgrading from free or cheep software to the industries best and most stable stop motion software but have held out, congrats, costs have not gone up and the latest version should have everything that is currently loved with an even better camera support then before. Dragonframe 4 is out and and it costs the standard price of $295, or now $325 with a Bluetooth controller rather then the corded controller.
