    zsh, particularly with extensive customizations and plugins, can consume more system resources (memory and CPU) than simpler shells like bash.
  • Inconsistent Behavior with Legacy Scripts
    While zsh is largely compatible with bash, certain edge cases and legacy scripts might exhibit inconsistent behavior, potentially necessitating script rewrites or adjustments.
