The bigger the black hole, the safer it is to fall in.

A black hole's size is really its mass. The event horizon is the edge: cross it, and no light, no signal, nothing you do can ever get back out. What tears a falling body apart is not the horizon itself but tidal force, the difference between how hard gravity pulls your feet and how hard it pulls your head. The closer you fall, the wider that gap. Most people assume a bigger black hole is the more violent one. The truth runs the other way.

What kills you is the gravity gradient, not the size. The tiny one is the killer.: Small black hole · torn apart, outside the edge · Supermassive · crosses whole, feels nothing

Tidal force grows as the gravity gradient steepens, which happens fastest close to a small mass. Near a black hole a few times the Sun's mass, the pull on your feet so outpaces the pull on your head that you are drawn into a thin strand of yourself, an effect physicists call spaghettification. It happens far outside the horizon, while you are still in open space. A supermassive black hole inverts this. Its horizon sits millions of kilometers out, so the gravity gradient across a body there is almost flat. You could drift across the point of no return whole, feeling nothing, already lost.

The largest black holes let you cross the edge intact. The small ones tear you apart first.
