It'll depend on lots of factors.
What the 72(t) account is invested in.
When the person did the 72(t) program.
What they chose for method and interest rate.
If RMD method, how old they were.
If they switched methods, when they switched and what the balance was.
How long they did the 72(t) for.
On average most folks probably did OK, because anyone sophisticated enough to try a 72(t) probably understands things pretty well.
One can always switch to the RMD method, and there are no longer penalties for a 72(t) program where the 72(t) balance goes to zero. So that's nice from a tax point of view, and means there's no drawback otherwise to starting a 72(t) - there's still the issue of running out of money of course.
I considered a 72(t) for next year since I just turned 54.5 last month. I decided against it; there's a thread I started if you're interested in the details of that thought process.
