Impact wrench, it is much safer and cheaper.
When using a cheater pipe/breaker bar to remove, for example, an axle nut, you can lose your balance when the fastener comes free or something breaks. You can fall, smash your face on the fender, break your nose and a tooth, and run up $6,000 in medical and dental bills.
Don't ask me how I know this.
Sorry, the incident is not on YouTube.
