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.
Happy hunting.
