As of 2018-09, there are 2 variants.

Romer-G Tactile. (this is the original Romer-g. Year 2015.)
Romer-G Linear. New, in 2018.

Characteristics:

Romer-G switch has hollow stem. This allows LED to be placed in center. So that key light can shine brighter thru the keycap's translucent label, and without light leaking at bottom.
Romer-g switch is noticeably more quiet than Cherry MX brown switches. Similar to the Cherry MX silent red.
Romer-g switch is supposed to last even longer than Cherry MX switches.
