FTCLib allows for a clean and efficient codebase with WPILib functionality. It also has its own trajectory generator based on WPILib but that generator is not as well-documented as Roadrunner for now.
Roadrunner allows for trajectory generation and visualization, and thus is far better than a time-based system (Roadrunner is waypoint-based with splines and PID)
