FF Marten.
More Would Be Less
This typeface, based on a simplified modular principle, produces shapes that are very clear and straightforward. The round endings of the non-Grotesque styles give it a somewhat friendly edge. The Grotesque styles are harder and show more detail in their character shapes.
The Cyrillic version contains a standard Cyrillic encoded font and an extra version according to the Adobe and Apple standards. Quite a few characters of the Cyrillic are drawn a bit more traditionally.
My next font was FF Rekord, a big contrast to the rather clean FF Marten.
