Which should you choose?
The Band V-Up gives accommodating resistance that peaks at the top of the range. The Cross Body Crunch needs no equipment and scales through leverage, tempo and reps. 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.
