Pick OllyDbg if…
It suits Windows users analyzing binary code without source, particularly those who need debugger tracing, breakpoints, or plugin support. Its frozen development status and incomplete 64-bit version are important considerations.
Pick pyOCD if…
pyOCD suits developers working with Arm Cortex-M microcontrollers who need command-line or IDE debugging, firmware programming, or a Python API for custom tools. It may also suit teams using CI or remote probe access, provided they account for the security and erase limitations.
