One of my big takeaways from CS classes was that goto loops are more efficient than for loops. So I'd start with comparing that with a recursive function.
Gosh I hope to hell you're being sarcastic because that's one of the worst takeaways you could probably get.
Technically, for performance, machine code has a higher performance ceiling than code produced by a compiler... but it's so fucking likely that you're going to make an error, either logically or in terms of performance, that machine compiled code almost always out performs hand written assembly written by gurus.
In terms of goto vs. for... gotos make it extremely easy to accidentally leave or enter functions without pushing or popping the appropriate frames so it's highly likely you'll end up introducing a really hard to track down segfault... there are better excuses you can find to learn
gdb.Gotos are generally avoided wherever possible in modern programming.
They make the code a lot harder to read and reason about.
With modern compilers I seriously doubt there's a huge difference.
But generally you want your code to be readable first and optimised where needed.
