Comparison
Suction-cup vs strapless dildo.
A suction-cup dildo is built for hands-free solo: stick to tile, sit / squat. A strapless (double-ended bulb) dildo is built for harness-free partnered penetration: one end held internally by the wearer, the other end used. Different geometry, different jobs.

The verdict
Suction-cup if the primary use is hands-free solo or shower / bath. Strapless if you want partnered penetration without a harness. They are not direct alternatives; choose by the scene you actually want, not by material or price.
