Am I correct to assume that the Tile will be higher than the Pergo? Is it too difficult to level both floors? That way you could use some grout or caulking to fill the gap, no need for marble thresholds. Unless you really want to use them?
I believe 1/4 inch is way too big of a difference for the thresholds to look leveled/good, they may even be a trip hazard.
