I recommend maildir, especially starting from KDE 4.8 and probably 4.7.2. :) 
With 4.7.1 I'm not sure it is better maildir vs. mixedmaildir. It is not 
about code quality, but the fact that mixedmaildir's code is obviously more 
complicated as it has two deal with both mbox and maildir structures.

The safest is to create a new maildir and point it to the existing maildir 
folder. Unfortunately this will results with all mails marked as unread if 
you use 4.7.1 or prior and even with the fixed maildir in the upcoming 4.8 
mails you received since you use KMail2 will be marked unread.
You will also need to adapt your filters to move/copy the mails to the right 
folder.

As a summary: wait until 4.7.2 or 4.8 is released and switch to maildir.
