Mysterious Killer

Due to the symmetry I had to find a way to disambiguate the grid, so there's an extra constraint this time. My previous similar puzzles are definitely more approachable.
- Normal sudoku rules apply: Place the digits 1 to 9 once each in every row, column, and 3x3 box.
- Unique Killer Cages: Within a cage, digits don't repeat and they must sum to the small number written in the top left of that cage. Additionally no digit may be used more than once among all the cages of the same sum, even if that sum is not explicitly given.
- Renban OR Nabner Lines: The lines in the grid are either ALL Renban lines OR ALL Nabner lines. Digits on a Renban line form a sequence of consecutive digits, but can be in any order. Digits on a Nabner line cannot be consecutive with any other digits on the line.

That was intense. Definitely a 5/5. Once you get started it does solve smoothly.

Very nice, although almost impossibly hard. It took me almost 7 hours to solve it logically. I am exhausted and satisfied. Thank you!
