Not too difficult. I expect it was much harder if you were trying not to use the X. I did use the X on several occasions and enjoyed this one. Not too difficult.

Fun! :) I did the puzzle without needing the X, but I did use the unique rectangle advanced technique with the 8-sum domino cages in the middle. ;) Killer Sudoku and CalcuDoku/KenKen are my favourite types of puzzles because the clues given in the puzzle unlock a plethora of other clues which crack the puzzle. And it is fun to find more than one way to come to the same unique solution. And the maths helps as well! :D Yum Yum! Fun! :)
