Hi, yes I have both and they are very comparable in mildness, but both efficient enough to deliver a bbs or near enough shave.
They are both ideal daily shavers that benefit a sharp blade.
ln terms of smoothness and comfort, I would just about give it to the Krona, it’s lighter and more nimble than the bulkier Sticky.
They are different enough though to justify an inquisitive purchase imo.
I've used both and would say that the Krona with a plastic knob is pretty much par with the Sticky, whilst the metal knob Krona is just a smidgen more efficient. The other key point about the Krona is that the angle on the blade doors guides you to the correct angle for shaving, so it works much better if you are in 7am autopilot mode
