About 18 months ago I made a video and posted on HybridPhoto.pro & You Tube that posed that very question.
At the time, while being very hopeful that mirrorless would allow me to replace my DSLRs, I felt that the cameras weren't quite ready for me.
All that changed when Sony announced the release of the a6000 camera and the 70-200 f4 G OSS FE lens.
Within minutes of testing this combination, I knew that I had found my answer.
Further testing with it only made it more clear to me that yes, this would be my new system.
This video explores the four criteria that I used to decide if the time was right for me to make the switch.
I hope you find this video helpful if you are in a similar situation.
