Maintenance
Maintenance and long-term fit
Do not compare only sticker price or the first setup step. Compare the whole workflow: measuring, buying, cutting, installing, finishing, revising, maintaining, and repairing the result. A cheaper or faster option can still lose if it creates more waste, harder cuts, weaker fastening, worse appearance, or more rework after the first mistake.
