The multiblade razors really work. Much less irritating, I think because the pressure of the razor against your face is divided by the number of blades. It makes it so no single blade can dig into you.
For me, the multiblades were always worse than the electrics.
The gave me a close shave, but the ingrown hairs weren’t worth it. Tried them off and on over the years, but I never tried the single-edge safety razor until recently and won’t go back to multis or electric.
