Considering the actual durability, the titanium version is more wear-resistant, and the paul smith version is the same as the ordinary version. But in fact, few people use X2 in extreme environment, so the difference of materials may be only slightly different in touch and psychology.
If it is out of the consideration of appearance color, then this is a very subjective aesthetic tendency problem. Among many versions of X2, I personally think that the white paper version or the silver-white version is the most beautiful, followed by the red leather version and the yellow titanium version. Of course, you must also have your own color preference;
If it is for the purpose of collection, it should be clear that digital cameras have no market collection value because electronic components are easy to wear and age, so they can only enjoy or show themselves. Among many editions of X2, the red cover edition, paper edition and Yokohama edition, which are limited to 20 to 30 sets, are the most rare. Paul smith edition limited 1500 sets. The titanium version belongs to the "customized version". Users can choose their own leather colors (ten, compared with five official colors) and carve their own signatures, patterns or badges on the fuselage. In terms of fashion effect and popularity, paul smith's version has more advantages. However, the titanium version can be "unique" and has great personality (if you buy a ready-made titanium version with color matching, you have not enjoyed customized service);
If you just want to buy a "portable" and "fixed focus" Leica X series camera, I recommend you to pay attention to the new Leica X (typ 1 13), which is an upgraded version of X2. Although the volume and weight have increased slightly, the aperture has been upgraded from f2.8 to f 1.7, and the lens is no longer telescopic. The mechanical focusing ring increases the focusing scale. The price will not be higher than paul smith's version.
To sum up, the titanium version is made of special materials, which is more wear-resistant, suitable for users who don't care much about the machine, and can also design the body color matching and local details through customized services. Paul smith version is a customized version of paul smith himself, which is more fashionable, emotional and eye-catching. These two versions are not as low-key and practical as the ordinary version in humanistic photography, but there is no harm in taking pictures of scenery. As for which of the two is better, we can only say that the dual brands of paul smith and Leica are more easily recognized by the public and will look better in the eyes of others, while the customized version (including the customized version of titanium top cover) is more meaningful to ourselves. In terms of functions, the newly released X (typ 1 13) can be given priority.
