The Olympus M.Zuiko 30mm f/3.5 Macro and the TTArtisan 40mm f/2.8 Macro side by side, computed from this guide's catalogue.

Which to pick

Pick the Olympus M.Zuiko 30mm f/3.5 Macro if you want autofocus and a design for Micro Four Thirds, which usually means smaller and lighter. Pick the TTArtisan 40mm f/2.8 Macro if you want a brighter f/2.8 (0.6 stops more light), for dim light and softer backgrounds; coverage of APS-C, so it suits the larger-sensor bodies too; and a fit on more cameras (180 against 49 in this guide).
