I switched to OpenShot about 2 months ago after working exclusively in Premier Pro for 3 years. I made the change because the price I paid for Premier simply wasn't justified for my video needs. I had looked at many free editors in the past and never found one that could handle 1) variable framerate, and 2) .MOV with transparency. OpenShot does so with very little trouble. It took me a little while to adjust to the UI and shortcuts, but I'm doing daily videos with minimal editing, and my editing time is comparable to what I experienced with Premier Pro. The only thing I "miss" from Premier is the built-in audio de-noiser... but I was using it as a crutch for poorly captured in-camera auido and have since fixed my audio setup.
