Tiling

Quoted 2 very different solutions for laying Marble Tiles

I want to have a Marble tiled floor in a 10 sqm ground floor room with a floating floor. Currently the top layer is chipboard. I've had two pros to assess the job; each giving a different solution: 1. Lay 18 mm ply on top of the floating floor (to reinforce the floor and allow even weight distribution of the tiles); then flexible adhesive; then the 15 mm marble tiles; finished off with sealant. This will raise the floor level to all surrounding rooms quite significantly and all will need to have adjusted thresholds. 2. Lay anti-crack matting on top of the floating floor (they declared the floor firm and stable and perfectly able to take the weight of the tiles by jumping up and down on it and feeling no 'bounce' or movement); then lay flexible adhesive; then the 15 mm marble tiles; finished off with sealant. (There was primer thrown in there somewhere but I obviously wasn't paying enough attention.) Both are natural stone, professional tilers whereas I am completely clueless. I need a casting vote that isn't OTT, or based on the cheapest/easiest solution, but is a practical, good quality and long-term solution that will justify the price.
