Thats the only problem with using grip adhesives, they make the job faster to fit, but it can be a pain if you ever come to remove them. With screws it's just a case of finding the screws with a magnet, then digging out the filler to remove the screws and then the skirt comes off easy. If you have a multi tool then you could score along the top[ of the skirt as deep as the skim and that should avoid any damage. You could use a magnet to find the nails and then hammer them right through the skirting board with a nail punch. Then tap a scraper in behind the skirt and carefully work along breaking the glue joint. The skirts will be lifted up by the thickness of the laminate and underlay, so that should cover any minor damage.
I mean if you like the look of scotia bead then go for laminate. It doesn't look too bad if you do a neat job with it.
