The short version

Each has a real cost: 7-Zip windows-centric GUI design; native graphical interface is Windows-only, with no first-class macOS or Linux GUI applications provided; Kap it has no annotation tools at all, so any still-image markup work needs a separate app such as Shottr or CleanShot X.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

7-Zip

Windows-centric GUI design; native graphical interface is Windows-only, with no first-class macOS or Linux GUI applications provided
Linux and macOS support primarily through command-line tools; no native file manager integration on these platforms
User interface design is dated compared to modern alternatives; visual feedback and UX polish lag behind commercial archivers
ARM64 support limited to Windows; no ARM64 build for Linux or macOS despite growing ARM adoption
No built-in cloud storage integration or synchronisation; cannot extract directly to Dropbox, OneDrive, or Google Drive

Kap

It has no annotation tools at all, so any still-image markup work needs a separate app such as Shottr or CleanShot X.
There is no scrolling capture or OCR, features both Shottr and CleanShot X include.
Editing is limited to basic trimming, so anything beyond a simple cut needs a dedicated video editor afterward.
It is Mac only, offering nothing for screen recording needs on Windows.
As a volunteer-maintained open source project, updates and bug fixes depend on community contribution rather than a company with paid support obligations.
