I made some quick shots around the house with the TTArtisan 50/0.95 choked to f/1.4 and the Summilux 50/1.4 wide open.
The results may impress you.
In the bokeh department it is difficult to force the lenses render differently!
In some results not pictured, the TTArtisan lens may suffer from more field curvature, the Summilux keeping up with the paper-cut image closer to the edges.
In the colors, 50 'lux does a colder presentation much to Leica's characteristic.
In ergonomics 50 Summilux wins handily, being lighter, having better focus ring (with a focus tab and short throw, just the way I like it) and having a builtin hood.
In build quality, frankly both are excellent.
More sample comparisons may follow.
The results may impress you.
