Ready Brake which combines the tow bar and brake is popular and less cost. Add magnetic lights for a super easy installation. Numerous posts on it.
Pros and cons to the different types. I've never regretted my adjustable tow bar for hookup. Installing are removing the big box brake got old after a few years so I switched to a permanent brake in the CRV about 2006. The used jeep came equipped for towing. GD has the CRV for college and it's still ready to be towed. I've always had wiring for the lights so just plug in the cord.
Note: Some toads require a charge line, some don't. Base plate installation access can be involved depending upon the vehicle. Access for wiring may be easy or not so much.
