I have a hard time with TTF because it's quadratic so I've totally skipped it for now and stuck with OTF only. I have tried the auto conversion from OTF to TTF, aside from it generating a ton of nodes, I figured the only way for it to look right was to manually clean it up to have fewer nodes, another reason why I skipped a TTF version. I'm not sure if fewer nodes is better for TTF or if an autoconversion is good enough, but the whole quadratic thing just made it difficult since I wasn't used to it. So are there any use cases where TTF is an absolute must that an OTF won't suffice or can I stick to just an OTF? Only thing I can think of is hinting but aside from hinting anything else?
