What’s More Effective: 1 Bigger Workout Per Week vs 2 Smaller/Less Intense Workouts Per Week?

Curious what people think is more effective: Option 1: 1 bigger workout per week + 1 long run + rest all easy runs Option 2: 2 less intense workouts per week + 1 long run + rest all easy runs

Has anyone ever experimented with both? One argument in support of option 1 is you can have an additional easy run day for aerobic gains. The argument in support for option 2 is a more frequent stimulus.
