Compare your needs: portability (phone/watch), accuracy and rules support (desktop apps), or remote synchronization (networked clocks). If you regularly play tournaments, prefer a minimalist, reliable clock (Lichess Clock or Chess Clock web). For customization or club use, desktop apps or DIY solutions shine. For remote play, choose a network-synced option.
