Using Designer UI files rather than handwritten C++ code has some advantages:

even quickly test with different styles and fonts.

+ Anyone, even non-coders, can make changes to the layout. Think people from

more with the XML than just converting it to a C++ source file.

+ One day KDE might use QtUiTools and load some UI files at run time, so be 
prepared :)

Some disadvantages should not stay unmentioned:

- It may add some bloat (e.g. code created by Designer currently sets object 
names for every layout or spacer, even if you never need a name there)

- Keeping the .ui file and the accessing .cpp in sync may require some more 
care because of the multiple files you have to check.

Can you please state your "own reasons"? If there is anything wrong with 
Designer, you can still "hand code" .ui files. Actually, I do this quite often 
myself, especially when doing small changes. Kate has nice XML syntax 
highlighting :)
