PostScript outlines in OpeType fonts are fine.
It just won't be as sharp as TrueType with instructions. But that is
alright for some people (using Mac OS X or similar antialiasing) and
depending on what medium you're using (high DPI device, paper, ...).
For most people, TrueType with high quality instructions is the best.
So if the targetted use is :
- lots of (small) text for most screens : use OpenType with TrueType
outlines with instructions;
- anything else : use OpenType with Postscript outlines with hints.
When working PostScript/CFF is actually easier to deal with. Edits are
a lot faster. So you'll probably want to design with those and then
convert it to TrueType outlines if you need to add instructions.
Working with Spiro also make things easier, but Fontforge still uses
PostScript or TrueType outlines in the files.
