What to use on previously painted concrete Lanai deck?

Lately, most are done with driveway type pavers in sand with only the perimeter and the coping stuck down. One company wants to use 1/2" tiles in Travertine, rough up the surface and adhere it all down, then grout. They both seem to look very good, but does anyone have an opinion on either ?
