Gotta be electrocution, limbs snapping is much more agonizing and takes longer

Lmcarth, I've been electrocuted before and I've had my bones deliberately broken as well. I would definitely take death by electrocution over being tortured to death via bloodbending.

Die or have all of your limbs forcibly broken

One is extremely painful but survivable, the other is instant death

Even though I hate pain, I love living so...

Yakone. At least you are not going to die.
