I've liked using a smooth, polished steel on lower/mid-50s HRC stainless blades, to keep them crisply cutting without needing frequent touchups on a stone. Kitchen knives like Victorinox benefit from this, because they'll take such fine edges in the first place, and are ductile enough that smooth-steeling will keep them aligned for quite a long while, before needing more work.
I've fiddled around with a grooved steel on other kitchen blades, and it works out OK at times. But there's a very fine line between benefitting the edge and detrimentally changing it, with a grooved steel. Used improperly, or too much, I tend to believe they do more damage than good, as compared to using the smooth steel, which is much more forgiving.
