I recently compiled a list of humanist slab serifs, the category into I would put Soho except that I see it as more cold and mechanical (“modern”?). Here goes (all fonts available on MyFonts.com unless otherwise listed):

Silica (Stonetypefoundry.com)
PMN Caecilia
Enclave (Terminaldesign.com)
Chaparral
TheSerif (Lucasfonts.com)
ITC Officina Serif
Amasis
FF Olsen
Placebo Serif
Aptifer Slab

EDIT: And how could I have forgotten Stag from Vllg.com?

How do you try out Stag? Nevermind found it

Morgan Avec also from Village.

Is there one that contains a hint of Quint like serifs? Amasis is very close.
