The case for lever connectors
The biggest win is consistency. A lever either clicks or it doesn't. No judgment on twists or torque. For service calls, open the lever, pull wire, test, reconnect. No cutting or re-stripping. On commercial jobs with hundreds of connections, time savings add up to hours.
The case for wire nuts
3-5x cheaper per connection. Universally available. Fit easily in tight boxes. 60+ year track record when properly installed. For budget-sensitive residential rough-in, wire nuts are perfectly valid.
Recommendation
Lever connectors for commercial, service/maintenance, and solid+stranded mixes. Wire nuts for high-volume residential rough-in where all conductors match.
