Laowa 17mm f/1.8 MFT vs TTArtisan 23mm f/1.4

The Laowa 17mm f/1.8 MFT and the TTArtisan 23mm f/1.4 side by side, computed from this guide's catalogue.

Which to pick

Pick the Laowa 17mm f/1.8 MFT if you want a design for Micro Four Thirds, which usually means smaller and lighter. Pick the TTArtisan 23mm f/1.4 if you want a brighter f/1.4 (0.7 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).
