Several comments here ring true. They open softer, have less lift, have far better flow through for higher speed deployments. They are smaller than an equivalent hemispherical chute even with a 15% spill hole. The side openings act as large spill holes.
It is especially important to make sure the lines are properly positioned or it spins.
Any chute on a heavy potentially high speed deployment rocket should use a slide ring like a key ring or reverse wound masking tape.
