They are both nice designs, but I think I like Miller the best.

I think they just both come from the same place.
Sørensen knows better than to take unfair advantage.

They're in related styles, both referencing historical models

Yeah, I certainly agree with the both of you after further research. But instantly I thought it heavily resembled Miller which is why I wanted to ask for your opinions.

but to my eye at least, much more not in common

You're not alone there. I can see the differences between the two but there are similarities for obvious reasons.

Hopefully I didn't come across as attacking Claus or his hard work.

Hi there. I started design on what became Playfair, as my first stab at typeface design for Gerard Unger’s class when he was teaching at the Rietveld. That was back in 2008. At that time I knew nothing of Carter’s Miller, only Georgia I did know, and later found out how it was derived from the Miller design (or was it the other way around?). In any event, at that time there was no particular inspiration for my proto-design.

Where Miller is much closer to the historical ‘scotch romans’, my Playfair is much more of a conglomerate. You can read more about the sources of inspiration on my website, but I did not mention there that also Caslon was an inspiration (eg. the C). What I did do was to think that the large x-height and slightly condensed letter shapes of goût hollandais would probably also be a good idea for a typeface meant primarily for screens, and that I hadn’t seen that done before (not really counting something like ITC Garamond et al.) done in a transitional design.

So was Playfair inspired by Miller? No is the short answer. If anything, it’s present form was inspired by the original specimens of Caslon, Baskerville, Fry, Miller, and Wilson which I viewed at St. Brides.

is it possible to obtain an OTF version via Google or otherwise? I've been able to download the TTF files (which look great!), but it said somewhere other formats should be available as well... Google's instructions were no help either:

You can also download specific source files directly from this Google Code Project website.
The 'browse' interface of the Google Code Project website doesn't handle as many sub-directories as this repository uses.
However, there is a work around - you can guess the folder name of the font family, and add it to the end of the browse URL, like this:
http://code.google.com/p/googlefontdirectory/source/browse/nobile
Note you can navigate to the 'src' directory on the left to find SFD, VFB and OTF source files.

...my various attempts at guessing the folder name failed (»nobile« causes a 404 as well).

awesome, thanks!
