Swiss type is the best type.
Grilli type foundry was featured on Typetoken a few days ago, check out their three amazing fonts GT Walsheim (from 2010 and already a classic), and brand new GT Pressura and GT Haptik. Haptik, above, was drawn by Reto Moser and Tobias Rechsteiner and is meant to be read by touch, thus the name. All three fonts are available in trial versions from Grilli.
