I have played both, and while I got bored of RW as soon as I got to the siege stage, I had to force myself to stop playing DF even though I still had about a dozen ideas for lava traps. YMMV.

Edit: I still have to stop myself from re-downloading dwarf fortress about once per week because there is so much left to explore. I just barely scratched the surface of power stations and automated rail systems. You could spend thousands of hours just designing traps to kill goblins. The fun is in the complexity. Perhaps you just did not get deep enough into the game. Now I have to talk myself out of downloading DF again. The sheer maniacal glee of knocking a dozen goblins off a narrow path (use a rail car attached to a pressure plate) into a pit and filling it with lava after spending hours setting it up just can't be described.

To be fair, RimWorld is a much newer game than DF. It hasn't had nearly as much time to add features.
