I primarily used Flinto the last few years but since Sketch 52 I've experienced a lot of bugs that sometimes makes the program unusable at times so I've switched over to Principle recently. I really like using the timeline in Principle and Flinto excels at micro interactions because of behaviors. Both still have a place in my workflow based on what my needs are per project. I bought a license for ProtoPie on Black Friday so I'm going to give that a try soon.
