The honest frame is to separate acquisition from analysis, because Elcomsoft and Sherlock sit on opposite sides of that line. Elcomsoft iOS Forensic Toolkit is an acquisition tool. It performs low-level extraction: a full-filesystem image and keychain decryption using checkm8 on devices up to the iPhone X range and an agent-based method that reaches newer devices up to iOS 18 and iPhone 16. It runs on macOS, Windows and Linux. Getting that data off a modern iPhone is hard, specialized work and this page does not diminish it.
Sherlock Forensics iPhone Analyzer sits on the analysis side, for iPhone and iPad, on Windows. It does not acquire a full-filesystem image and does not run checkm8 or an agent; its own acquisition is a logical iPhone backup. For anything deeper it reads an extraction that another tool produced, then works the artifacts and writes the report. So the comparison is not which tool is better in the abstract, because they do different jobs. It is a narrower question: once you have an iPhone extraction, do you need a second specialized acquisition purchase to read it or does a focused analyzer at a one-time $599 cover the analysis and reporting.
