If you sell the 21mm for the 24 Canon TS, all your wide angle work will be made by Canon, for whom you rely on to produce images at not even one other focal length up to 100mm. That is pretty remarkable in itself. So - Canon output for ultra wide, everything else Zeiss.
My views on Canon lenses are known and I'll not labour them except to say that all a person has to do is look at equivalent Canon and Zeiss (or Leica) lenses on the same Canon body to see what's what. What Canon produces is in the lenses. So just one opinion: colour separation might not to be a high priority for Canon lens designers.
Based on what you use, you might be a person who looks for overall high impact, colour balance and high appeal in images. You simply have to decide what you really want, what is the priority..here is one way - take a look without bias at 'your best' 10-15 images shot with the two UWAs you have; then tally them up, see what falls out. If the Canon 17mm gets even close to the 21mm count, there is the answer.
In almost all respects the 15mm is the equal of the 21mm and in several it is better - lower distortion, more even across apertures, and its own kind of liquid clarity. Zeiss guaranteed MTF results for each one of the first release of these lenses...I figure if people don't have an emotional response to the images from the better modern Zeiss lenses (Like Simon above), they are candidates for OEM C/N lenses.
The 15mm is an expensive lens even for CZ, it will hold value extremely well and prob rise with new high Mp sensors, it lacks the fashionable bubble element (a design intent) and takes standard filters. The chance to get one for cheaper looks very good.
You could look thru' the 15mm CZ thread, and I just saw two threads for the 17mm TS lens in the (foreign to me) Canon forum, one surprisingly about using these lenses with teleconverters.
