Making OpenType Fonts

What Format to Prefer
It is not easy to say which version is better. Both formats will work on both
platforms. For Windows-centered office use we would recommend TT-
flavoured OpenType fonts, as they will provide better compatibility with
the old versions of the OS.
For cross-platform and DTP-oriented applications the CFF-flavoured
version seems to have some advantage because it will provide better basic
rendering quality.
Please note that the differences are minor and the most important thing to
choose is the source format in which you have your fonts. If you have
TrueType fonts that you want to convert to OpenType format by adding
features, then the TT-flavoured format is your choice.
If you have Type 1 fonts, it will be easier to convert them to CFF-flavoured
OpenType format.
