Reputation

iTerm2 is widely regarded as the leading terminal emulator for macOS among developers and power users due to its deep customization and productivity features. It receives regular updates and has a large user base. Some users report occasional performance issues with very large scrollback buffers or complex tmux sessions. Its exclusive macOS focus limits portability.
