Adobe Premiere Pro or Final Cut Pro are still considered the gold standards for video editing, but they do have fairly steep learning curves if you want to produce highly professional output with numerous tweaks to video quality.
I used to use Windows Movie Maker as a "quick and dirty" editing app and it did a great job. Too bad Microsoft decided to drop it from Windows 10. I've been using CyberLink's PowerDirector since then because it has a simplified interface like Movie Maker, but unfortunately the output files are very hit-or-miss when played back on various laptops with different CPU and GPU hardware (ie, some are very smooth but some are very jerky).
