WinRAR vs 7-Zip Encryption
RAR5 and 7z are both modern archive choices, but their metadata and error behaviour differ. Comparing them is only useful when it leads to a concrete diagnostic and recovery plan.
What they have in common
RAR5 and 7z both use AES-256-based protection and key derivation intended to make password guessing expensive. Both are perfectly secure against recovery when the password is long and randomly generated.
Both formats are also used with human-created passwords. In those cases password history and a bounded candidate plan matter more than a generic speed table.

Where diagnostics differ
RAR5 users often meet split volumes, recovery records or checksum errors. 7z users often meet hidden headers, missing split parts, or data errors after authentication. The error vocabulary is a better starting point than the extension alone.
Run each utility's integrity test on a copy and keep the exact output. Do not translate a RAR repair record into a 7z recovery assumption; the formats have different structures.
How to choose a service or local tool
Choose a workflow that explicitly supports the format generation, verifies a recovered candidate by extraction, and explains retention and pricing. If the archive is incomplete, solve the data problem before paying for a password search.
