SSH, SFTP, and serial, cross-platform, with the safety checks most terminal clients skip, and none of the busywork of the ones that don't.
Trust-on-first-use with a genuinely different warning when a key changes, not the same click-through dialog for a new host and a possible interception.
The same terminal, the same feel, on Windows, macOS, and Linux. Real installers for each, not a compile-it-yourself README, so switching machines never means relearning a new app.
Six color-scheme presets, eleven fonts, a wallpaper behind the prompt. The kind of thing you actually look at for eight hours a day should look like yours.
