There is no single "top" or universal unpacker for VMProtect 3.0 because the software uses sophisticated virtualization and mutation that cannot be defeated by a simple click-and-run tool. Instead, reverse engineers use a combination of specialized open-source tools and manual debugger scripts depending on the specific file type (.NET vs. Native C++) and the level of protection applied.
: Search for "VMP3 Unpacker" on GitHub for scripts that automate the IAT fixing for specific versions.
No script can brute-force VMP 3.0's anti-debug. The "top" way to even touch the unpacked code in memory is using kernel-level hiding.
