Which should you choose?
The 3/4 Sit-Up needs no equipment and scales through leverage, tempo and reps. The Cable Judo Flip keeps constant tension on the muscle through the whole range of motion. If your gym has both options, neither is a wrong choice: pick the one that feels strongest through a full range, and swap after 6 to 8 weeks to keep the abs adapting.

Choose based on your equipment and which movement you can progress consistently.
Can I do both the 3/4 Sit-Up and the Cable Judo Flip in the same program?
