The problems I've seen with tile floor are all related to vibration; cranking tile, cracking grout etc. Some of the bridge expansion joints I've hit would jar loose filings in my teeth.
Tile is cold on the feet and should be heated for comfort. Take that into account when pricing the job.
Floating vinyl here. one year, no issues.
