There’s really no point in having two fully-populated quadruples clues in a box. They only touch seven cells between them, so giving you four digits is overkill.
Rules:
Normal Sudoku rules apply.
Digits within circles appear at least once in cells touching the circle.
Sudoku-X: The marked diagonals each contain the digits 1 to 9 exactly once.
Estimated difficulty: 1 out of 5
