 While Ti is stronger than steel, it is very slightly softer than steel (depending on alloy and surface treatments such as tegimented steel or Duratect). The finish of a watch has a lot to do with how much the scratches show.

The advantage of Ti is that scratches oxidise over time and tend to fade into the background as a result. The TiO surface layer exists on all untreated Ti alloys and is very inert - and is responsible for the darker appearance of Ti cases.

IME, brushed Ti can be 'repaired' with a fiberglass brush and in days to weeks the repair will be nearly invisible. In this way, the advantages of Ti for a dive watch case (doesn't corrode, hypoallergenic, strong, light, etc.) outweigh the disadvantages.
