autohint, because longest straight lines in some glyphs such as 'g', 'a',
'B', 'f', etc., are rendered too wide (similar to hintnone). On the
contrary, using BCI with hintstyle=hintfull (likewise for hintstyle=hintmedium)
causes some parts of glyphs fonts to be too thin (see 'R' for example).
So, the best combination seems to be autohinter with hintstyle=hintfull.
