I like Didot and was hoping to have my web designer use it on my website. My one hesitation is because it is such a high contrast font that it doesn't look as nice small as it does large. I came across H&FJ Didot which has "Optical Sizes' which is a concept I really like, but since I am not a graphic designer I don't know how big of a difference the "Optical Sizes" will really make on a website. I really only will need at max maybe 8 styles of Didot, but the H&FJ Didot only sells theirs in a package of 42 styles (because of the optimized fonts) so it is quite a bit pricier than other Didot fonts I have looked at (like Linotype Didot on myfonts.com)
I really like Didot, but I know enough about graphic design to know I don't know graphic design and that is why I am asking to get a consensus of whether it is really worth it to invest the extra couple hundred of dollars to get the H&FJ Didot vs Linotype Didot?
Thank you for reading my question :)
