I think the big difference in adhesion to Kapton tape is how close the nozzle is to the heated print bed. if you have it the first layer squished on real good, it will practically never pull up and warp during the build, but is harder to get off when done. It is is just laid on for the first layer, it comes off easily but will probably pop off on a larger/longer print. There is a little finesse needed to get it "just right". On my Cupcakes, I adjust the first layer height on the run.
