panic(9) prints stuff, optionally drops into a debugger, and then 
calls cpu_reboot(9).

cpu_reboot(9) optionally unmounts file systems, runs shutdown 
hooks, prints a message, and halts or reboots.

It's dropping into a debugger that provides the most significant 
(and potentially annoying) difference in visible behaviour, but 
also you have more control over the boothowto flags if you call 
cpu_reboot(9) directly.
