The ambigrams have great visual appearance, some are very interesting, others not so much and of course not all would be good as corporate image.
There are with the same reading when rotating 180º and horizontal or vertical reflection:
Sometime ago some brands of companies transformed into ambigrams like Samsung or Oreo were published on internet. Logically, not all names give the same result to be represented like that.
Very few companies admit it as a corporate image: DMC, New Man ... Not even young and recently created companies.
1 - Ambiguity: the double reading leads to interpret a conceptually wrong ambiguity as a company image.
2 - Ignorance: the designer is unaware of its existence or did not think of it as a design possibility.
3 - Informality: can be interpreted with a playful sense and indicate lack of seriousness.
4 - Gimmicky: once played the visual game loses effect giving a sense of ephemerality.
5 - Comfort or practicality: it is much easier to choose a designed font.
6 - Discard: should be definitely excluded as a branding option.
As a practice, it is an excellent typographic exercise. Here my full name.
